Many of the celebrity hookups that the world knows about are juicy and sometimes pretty scandalous. But it’s the ones you haven’t heard about that are really salacious, surprising, and sometimes just straight up silly. Allow us to explain.
Amy Poehler and John Stamos
In October 2014, Amy Poehler revealed to Howard Stern that she went on a date with John Stamos shortly after separating from now-ex-husband Will Arnett. "It was new and weird. I hadn’t dated when there was texting. I got married in 2003 and all of a sudden I’m like, ‘Oh, right now you text somebody.’ That was new," she said. "There were times when I was out with guys and I was like, ‘Oh, I think I might be on a date, but I don’t know. I remember I was at dinner with John Stamos … handsome men are really something else. First of all, they’re so handsome. And John is [ridiculously handsome]," she said.
"I was at a restaurant. We were having dinner and I was like, ‘Oh, maybe this is a date!’ But I didn’t know. But I kinda blew it … We worked on a movie [They Came Together (2014)]. He did a little bit in a movie that I did and a bunch of us hung out. And then later on he’s like, ‘Let’s go get dinner. And it was fine. I remember thinking like, ‘Oh, s**t. Like, if this is really a date…’ I think I was wearing a Leslie Knope top. I think I was wearing a shirt from work. I wasn’t foxy."
Stamos clarified to Extra in December 2014 that it was, in fact, a date. "We’re really good friends," the Fuller House hunk said. "I guess [Amy] didn’t know it was a date. I asked her out on a date … and we had a really nice time. Then I hear she thought it wasn’t a date. It was a date in my eyes."
Leonardo DiCaprio and Naomi Campbell
Naomi Campbell was one of the very first supermodels to make it into Leonardo DiCaprio’s little black book. The New York Daily News reports that they dated briefly in 1995 before deciding they’re better off as friends.
Kim Kardashian and Nick Lachey
Nick Lachey rebounded from ex-wife Jessica Simpson with Kim Kardashian in 2006. He told Details (via Entertainment Tonight) that he thinks the reality starlet used him to raise her profile, because she wasn’t famous yet at the time.
"Let’s just say this: We went to a movie. No one followed us there. Somehow, mysteriously, when we left, there were 30 photographers waiting outside," he said. "There are certain ways to play this game, and some people play it well."
In her 2010 book Kardashian Konfidential, Kardashian admitted that dating the 98 Degrees hunk got her attention. "The next night I was out with Paris Hilton," she wrote. "We were in her car and the paparazzi started taking pictures. Usually they would shout, ‘Paris! Paris! Paris!’ [But] they started yelling ‘Kim! Kim! Kim!’ I wanted to hide, and Paris and I just looked at each other and laughed. She said, ‘Whatever you do, just smile.’"
Cher and Tom Cruise
In June 2013, Cher revealed on Watch What Happens Live that she and Tom Cruise had a fling in 1987 — and she loved it! When asked where he ranked among her lovers, she replied, "He was in the Top Five. It’s not a long list, just a good list." She described Cruise as a "great, lovable guy" and said they were "hot and heavy" during their brief romance.
In 2008, she told Oprah, "It could have been a great big romance, because I was crazy for him."
Cher and Val Kilmer
Cher’s son, Elijah Blue Allman, revealed that she dated Val Kilmer in the 1980s. "I really liked him," Allman told Contact Music (via Entertainment Tonight). "He gave me a real Indian scalp that’s like 100 years old."
Jay Leno and Sharon Osbourne
Sharon Osbourne revealed on The Talk in 2013 (via People) that she hooked up with Jay Leno in the 1970s. "When I was 25, I just moved to America. I had met my husband [Ozzy], but we weren’t together." She said a pal took her to a comedy club where Leno performed, and she said he was "very nice, very funny." She and her buddy prank called him. "He liked my voice … One thing led to another. He came to my house and met me and then we had a little fling. The fling was more fling for me and not fling enough for him."
Evan Rachel Wood and Mickey Rourke
Mickey Rourke played Evan Rachel Wood’s father in The Wrestler (2008), and the pair were rumored to have dated post-filming. Fox News spies spotted Rourke, then 56, and Wood, then 21, making out at a party.
Tara Reid and Tom Brady
In 2014, Tara Reid confessed that she dated Tom Brady for about a month in 2002. "I have kissed [Brady]," she told the Kyle And Jackie O Show (via Radar Online). "Yeah, he’s pretty good looking."
Jake Gyllenhaal and Minka Kelly
A source told Us Weekly that Jake Gyllenhaal pursued his crush, Minka Kelly, to no avail for a months until she finally caved in June 2012, but the hookup was short-lived. "Minka wasn’t into Jake when he first pursued her … [she later] decided to give Jake another chance … It was never serious, and it’s over now."
Janet Jackson and Matthew McConaughey
Because Janet Jackson is incredibly private, few details are known about her brief hookup with Matthew McConaughey. The pair reportedly met and hit it off at the 2002 Grammys and had a couple casual hookups before calling it quits shortly after. Alright, alright, alright!
Hilary Duff and Shia LaBeouf
Shia LaBeouf went on one date with fellow Disney alum Hilary Duff when they were younger, and it didn’t end well. He told Details (via Just Jared), "[It was] probably the worst date either one of us has ever had." Truthfully, this one is pretty disappointing, because we already came up with the couple name "Shia LaDuff" and now we can never use it.
Shia LaBeouf and Megan Fox
Shia LaBeouf told Details (via E! News) that he and Megan Fox hooked up when filming the Transformers franchise films. "Look, you’re on the set for six months, with someone who’s rooting to be attracted to you, and you’re rooting to be attracted to them … I never understood the separation of work and life in that situation. But the time I spent with Megan was our own thing, and I think you can see the chemistry onscreen."
Megan Fox and Robert Pattinson
When Megan Fox was on a break with then-boyfriend (and now-husband) Brian Austin Green, she hooked up with a then-single Robert Pattinson. An on-set source who worked on Fox’s movie Jennifer’s Body (2009) told E! News, "Megan was totally into [Rob] and thought he was really cute, but nothing ever went further than one night they were together. He totally blew her off."
Julie Bowen and David Spade
It’s hard to picture Claire Dunphy dating Joe Dirt, but it happened. Julie Bowen dated David Spade in 2002, and the pair stayed together for about a year.
Anthony Kiedis and Heidi Klum
Supermodel Heidi Klum had a brief fling with Red Hot Chili Peppers frontman Anthony Kiedis in 2002 as her marriage to Ric Pipino came to an end. Kiedis would later gush of Klum, "The time with Heidi is one of the most beautiful memories in my life. The hottest woman in the world was my girlfriend, that made me really proud. I saw her and immediately fell in love with her … [The relationship] was not very long, but was very intense. I was at that time a selfish ass, Heidi had just come from a broken marriage … A man can be happy, with a woman like her at his side. She is not only beautiful, but also intelligent, a successful business woman, and great mother. I was and I am still a big fan of her."
Scarlett Johansson and Jack Antonoff
Long before Scarlett Johansson was an A-lister and way before Jack Antonoff had a hit song and Lena Dunham on his arm, they were high school sweethearts. Antonoff even name-drops the Avengers (2011) star in his Steel Train 2005 song "Better Love," singing, "Hey Scarlett / You’re not the same."
Scarlett Johansson and Justin Timberlake
Justin Timberlake and Scarlett Johansson are rumored to have gotten hot and heavy on and off the set of his video for "What Goes Around … Comes Around." Spies told Us Weekly that the crooner got very close with Johansson in New York in 2011 while he was dating Jessica Biel. After party-hopping all night, JT reportedly headed right to Johansson’s apartment. A source told the mag, "They’ve hooked up several times over the years."
Justin Timberlake and Kate Hudson
After splitting from Cameron Diaz in late 2006, Justin Timberlake rang in 2007 with Kate Hudson. A source told E! News that Timberlake attended a New Year’s party at the Oscar nominee’s home, where they were "chummy" and "flirting and talking all night." A witness claimed that at one point during the party, the pair went upstairs together, and when Hudson came back down, she was wearing a different outfit … and that when everyone else went home, Timberlake stayed put at Hudson’s house. Okay!
Justin Timberlake and Fergie
In 2001, just before Justin Timberlake broke out with N*SYNC and when Fergie was in Wild Orchid, he was the cougar to her cub. "It wasn’t a long-term serious relationship," Fergie told Australia’s Courier Mail (via the New York Daily News). "He was 16 and I was 23. It was before he got real hot and heavy with Britney [Spears]."
Ashton Kutcher and January Jones
When January Jones first moved to Los Angeles in 1998, she dated Ashton Kutcher for three years — and claimed in a 2009 GQ interview, "[He] was not supportive of my acting. He was like, ‘I don’t think you’re going to be good at this.’" She later clarified on Watch What Happens Live that she hadn’t revealed his name in the interview … but it’s clear what and who she meant.
Natalie Portman and Moby
Moby dated Natalie Portman in 2001, and he admits it wasn’t easy. He told Spin (via the New York Post) in 2008, "I guess in some people’s eyes, [nerds] might be mildly sexy — and, as a nerd, I’m certainly happy to enjoy some of the effects of that. But as far as the very brief affair that I had with Natalie, it’s made me a target of a lot of nerd wrath. You don’t date Luke Skywalker’s mom and not have them hate your guts."
Ryan Reynolds and Kristen Johnson
Ryan Reynolds romanced Third Rock From The Sun star Kristen Johnson back in 1999. She’d later tell Andy Cohen on Watch What Happens Live, "I dated him for a few months. He’s great! It was when he was on Two Guys, A Girl, And A Pizza Place, if anyone remembers that, and I was doing Third Rock."
Sean Penn and Jewel
When Sean Penn was on a break from his marriage to Robin Wright in 1995, the same year her breakout album Pieces Of You hit shelves. She told People, "We dated for about a year, I was about 21, something like that. And I didn’t want to be known for who I was dating. But he was very lovely to me." The singer said that Penn introduced her to Hollywood heavyweights like Roman Polanski, Jack Nicholson, and Warren Beatty, and that he even followed her on tour. When they split in 1996, Penn reunited with Wright.
Julia Roberts and Matthew Perry
After Julia Roberts guest-starred on Friends in 1996, the five-time Most Beautiful Woman briefly dated Matthew Perry. However, it didn’t last long: The Daily Mail reports that the couple called it quits after just a few months because they couldn’t stop fighting.
Pink and Joey Fatone
A match made in pop heaven: Pink revealed in 2013 that she dated N*SYNC singer Joey Fatone in the early 2000s. She told Glamour, "Joey Fatone was in love with me. He took me to Friendly’s on a date and he bought me an ice cream. Such a sweetheart. He asked my dad’s permission!"
Lance Armstrong and Ashley Olsen
Ashley Olsen and Lance Armstrong got hot and heavy for a hot minute in 2007. Spies saw them getting very close and making out, with Olsen even sitting on his lap in public, for a few months that fall. The hookup fizzled, and Armstrong quickly moved on to Kate Hudson.
Amanda Seyfried and Alexander Skarsgard
George Clooney and Lucy Liu
Whispers of a romance between Lucy Liu and George Clooney first emerged around 2000, though they didn’t really take off. However, the pair rang in the New Year together in 2006, and their tonsil hockey got tongues wagging. One onlooker reportedly noted, "She looked like she was going to devour him."
Carmen Electra and Simon Cowell
Carmen Electra dated Simon Cowell from December 2012 to February 2013 … when she reportedly busted him getting a little too-close with his now-baby mama Lauren Silverman. (Silverman, as you may recall, was still married to Cowell’s best friend Andrew Silverman when they began hooking up.) Still, Electra only had nice things to say about Cowell later on, telling Loaded magazine (via the Daily Mail), "I just thought Simon was so much fun and was so smart and he’s really interesting … I think he’s awesome and very charming. He has such a great sense of humor and I honestly think he’s going to be an amazing father, I truly do. I’m sure little Eric Cowell will get a lot of knowledge of entertainment and business. He’ll absolutely have to take over the family empire. I can see it. I can picture him doing that."
Gene Hackman and Cloris Leachman
In her 2009 autobiography, Hollywood veteran Cloris Leachman wrote of a dinner date with Gene Hackman that, well, went right to dessert.
"As we moved into the main course, it was as if a cosmic wind enveloped us. Some giant space magnet was pulling us together," she wrote (via the Huffington Post). "We didn’t finish the meal. We went upstairs, flew into bed and made love. It was epic. And the next morning, Gene went back to his film and I went back to mine. I haven’t seen Gene since that night, but I remember well the feisty lad he was."
Rita Moreno and Marlon Brando
Rita Moreno had a torrid, on-again-off-again affair with Marlon Brando for eight years after meeting him on the set of Desiree (1954) when she was 22 to his 30 years old. She wrote in her memoir (via the New York Post), "Just meeting him that first day sent my body temperature skyrocketing as though I had been dropped into a very hot bath, and I went into a full-body blush. It was the sort of rush that inspires poetry and songs."
She added, "To say that he was a great lover — sensual, generous, delightfully inventive — would be gravely understating what he did not only to my body, but for my soul. Every aspect of being with Marlon was thrilling, because he was more engaged in the world than anyone else I’d ever known."
Unfortunately, the affair was not a happy one. She continued, "He broke my heart and came close to crushing my very spirit with his physical infidelities and, worse, with his emotional betrayals … I couldn’t stay away. In fact, I was becoming addicted to the challenge of winning him over and over again."
Within their eight-year romance, Brando married and fathered children with two other women and even pressured Moreno to get an abortion when it was discovered she was pregnant with his child. The melodrama led her to attempt suicide in 1962 when she found out Brando had fallen in love with his Mutiny On The Bounty (1962) co-star Tarita. Teripiia. "We were locked in the ultimate folie à deux, a crazy love that lasted for years, until one day I quite literally was forced out of a coma and had to choose life over him," she wrote.
Eventually, Moreno’s therapist begged both her and Brando to stay away from one another, and they finally agreed. In 1965, she married Leonard Gordon, who she called the love of her life — but Brando remained "the lust of [her] life."
