An Instagram model has claimed that she and Maroon 5 frontman Adam Levine had an affair in a shocking, now-viral TikTok.

Sumner Stroh made a claim that she had “an affair with a man who was married to a Victoria’s Secret model” when she was “young,” “naive” and “exploited” — and possessed alleged receipts — on the platform on Monday.

Stroh, who calls herself an “Instagram model” in the video and has an OnlyFans account, also alleged that while she and Levine no longer see one another, he reportedly messaged her asking her permission to name his unborn child “Sumner.”

In her video, which got more than 14.1 million views in a matter of hours, Stroh, 23, claimed the two were seeing each other for nearly a year, although the exact timeline is unclear.

Levine, 43, and model Behati Prinsloo, 34, have been married since July 19, 2014, and announced on Sept. 6 that they are expecting their third child.

When contacted by Page Six, Stroh claimed the alleged affair, which happened “last year,” was “physical, yes, but I’m not saying anything further.”

The Post has reached out to reps for Levine and Prinsloo for comment, who have not yet responded to the claims.

On Tuesday, Levine denied having an affair but admitted he “crossed a line.”

“I used poor judgment in speaking with anyone other than my wife in ANY kind of flirtatious manner,” Levine told TMZ in a new statement on Tuesday. “I did not have an affair, nevertheless, I crossed the line during a regrettable period of my life. In certain instances it became inappropriate. I have addressed that and taken proactive steps to remedy this with my family.”

“My wife and my family is all I care about in this world,” he continued. “To be this naive and stupid enough to risk the only thing that truly matters to me was the greatest mistake I could ever make. I will never make it again. I take full responsibility. We will get through it and we will get through it together.”

The saga began Monday when Stroh, who has over 338,000 followers on Instagram, posted a now-viral TikTok.

“Embarrassed I was involved w a man with this utter lack of remorse and respect,” she captioned the video in which she speaks about the allegations.

“At the time, you know, I was young, I was naive. I mean quite frankly, I feel exploited,” she said of their alleged relationship. “I wasn’t in the scene like I am now, so I was definitely very easily manipulated.”

Sumner Stroh made the claims in a shocking TikTok posted Monday.

Deeming Maroon 5 “practically elevator music at this point,” Stroh shared screenshots allegedly between her and Levine with messages she claims are from him.

“It truly unreal how f–king hot you are,” he allegedly wrote in the messages, which did not show exact dates. “Like it blows my mind.”

Stroh, who touts herself as a Texas alum online, claimed she stopped talking to the tatted Super Bowl halftime show performer, but he supposedly “came back into her life” with jaw-dropping Instagram messages in June.

“Ok serious question,” Levine allegedly wrote in messages that appeared on Stroh’s lock screen on June 1. “I’m having another baby and if it’s w [sic] boy I really wanna name it Sumner. You ok with that? DEAD serious.”

“I was like ‘I’m in hell,’” Stroh said of his alleged ask. “I have to be in hell at this point.”

Stroh said she never intended to make the alleged affair public, but a friend she said she trusted reportedly sent the screenshots and “attempted to sell [them] to a tabloid.”

“So here I am,” she somberly said.

“I was like ‘I’m in hell,’” Stroh claimed after Levine allegedly reached out to her again once they stopped talking. “I have to be in hell at this point.”

In an Instagram Story, Stroh acknowledged getting some blowback on social media about her claims.

“Aware people are going to try to fill in the gaps with many false assumptions. I don’t feel like I’m doing any favors considering the manner this had to go about,” she said. “It’s a lot to digest but hopefully, at the very least, the truth being out can do some good.”

Stroh also posted a “part 2” video late Monday night, which she deemed “necessary” since she feels “remorseful,” “embarrassed” and “disgusted” with herself.

However, the model responded to comments on TikTok questioning her intentions.

“Can I ask why not go to his wife directly and at least warn her before blindsiding her with a TikTok come out?” one person asked. “I tried,” Stroh responded.

“No one looks good in this story,” another wrote, to which Stroh replied, “I’m aware.”

“I’ve been sick about this,” Stroh responded to one user who criticized her, writing, “‘Manipulated’ that’s a groovy way of back dodging your percentage of blame.”

TikTok users had mixed reactions to Stroh’s claims.

“HE WANTED TO……NAME THE BABY….. AFTER YOU……….. is he okay????” one user commented about the allegations.

“OMG my mouth dropped to the floor when I saw his name,” another said. “Maaaan even Victoria secret models are getting cheated on smh no one is safe,” another added.

Others put the blame solely on the model.

“… but you knew he was married,” another shamed the influencer.

“It’s no secret he’s been married for a decade. The only victim here is his wife and children,” one user wrote.

“I was completely manipulated by a man I knew was married,” another mocked. “The jokes write themselves.”

“Messed up situation but there’s accountability that needs to be held on both sides,” another wrote with the side eye emoji.

“I think she forgot the apology somewhere,” another said of Stroh.

After reading and responding to several of them, Stroh said she would further explain the situation.

“I’m disgusted and so ashamed of the pain and hurt I’ve caused. I didn’t want to sound whiney so that wasn’t said in this video,” she wrote.
