Heartbroken Nick Carter addressed his “complicated” relationship with late brother Aaron Carter in a heartfelt tribute following the singer’s tragic death on Saturday.

“My heart has been broken today,” he began a lengthy tribute alongside a slideshow of photos of him and Aaron over the years. “Even though my brother and I have had a complicated relationship, my love for him has never ever faded.

“I have always held onto the hope, that he would somehow, someday want to walk a healthy path and eventually find the help that he so desperately needed. Sometimes we want to blame someone or something for a loss. But the truth is that addiction and mental illness is the real villain here.”

The 42-year-old Backstreet Boys member concluded, “I will miss my brother more than anyone will ever know. I love you Chizz., now you get a chance to finally have some peace you could never find here on earth….God,Please take care of my baby brother.”

Aaron was found dead in his California home on Nov. 5 at age 34.

“It is with great regret to confirm Aaron Carter was found unresponsive this a.m. in his home in Palmdale, CA,” the singer’s rep told Page Six at the time.

“The family has been notified and will be flying out to Los Angeles,” the spokesperson continued. “Aaron worked very hard towards the end of his life in recovery, to be a good father and to make amends with his family.”

Aaron and Nick have had a strained sibling relationship over the years, with the Grammy nominee requesting a restraining order against his younger brother in September 2019.

Nick posted a series of photos of himself with his little brother on Sunday.

“In light of Aaron’s increasingly alarming behavior and his recent confession that he harbors thoughts and intentions of killing my pregnant wife, [Lauren Kitt], and unborn child, we were left with no choice but to take away every measure possible to protect ourselves and our family,” Nick wrote in a statement at the time.

The one-year restraining order was granted in November 2019.

Prior to Aaron’s passing, the actor spoke candidly about his addiction struggles.

The “I Want Candy” crooner “started getting really heavy into drinking” after his time on “Dancing With the Stars” in 2009, he told Oprah in 2016.

“I was telling people, ‘I’m on a very bad path right now, I need help,” he recalled at the time. “I called my mother. She took me down to her house. The next day I was at Betty Ford [Rehab] Center.”

The following year, Aaron was arrested for marijuana possession and driving under the influence but avoided jail time.

Aaron subsequently got into a “terrible” car accident two months later that left him injured and his BMW totaled.

The rapper is survived by a son, Prince Lyric Carter, whom he welcomed in November 2021 with on-again, off-again partner Melanie Martin.

Despite the joyous occasion, the past year saw the “Aaron’s Party” crooner’s home life consumed with tumult on a near-routine basis.

A week after Prince’s birth, the musician and Martin, 30, broke up over what he characterized on social media as a “very big lie,” supposedly perpetuated by his estranged twin sister, Angel Carter.

Three months later, Martin took out a restraining order on Aaron following an argument in which she alleged that he punched her in the torso, cracking three of her ribs before throwing her and their newborn son out of his California home.

Martin, who got engaged to Aaron in June 2020, speculated that pills were behind Aaron’s alleged outburst.

“I think that during the days of our breakup, he took too many of his prescription pills and it gave him too much aggression. He probably doesn’t even remember he did so,” she wrote in March. “I think he needs anger management, counseling on how to control his anger. He is very jealous and needs to be more rational because he doesn’t even remember he did so I believe.”

Martin later backpedaled on her claims about Aaron being physically violent during the dispute, however, explaining via Instagram that she made up the “untrue” narrative due to postpartum depression.

The siblings had a tumultuous relationship, with Nick getting a restraining order against Aaron in 2019.

In September, the former child star confessed to The Sun that he was voluntarily attending an outpatient rehab program in light of losing custody of his son.

“I haven’t had any relapses or anything like that, it’s just triggers are big right now for me [and] I want my son back,” he told the outlet at the time.
