Aaron Carter recalled crashing at Michael Jackson’s home after a birthday celebration — only to wake up to find the pop star at the foot of his cot in “tighty-whitey underwear.”
The disturbing incident allegedly occurred at Jackson’s Neverland Ranch in August 2003, when Carter was just 15 years old.
Carter — who was found dead in the bathtub of his California home on Saturday — dished out details in his controversial new memoir, “Aaron Carter: An Incomplete Story of an Incomplete Life,” set to be published posthumously Tuesday. The Post obtained an advance copy.
“Michael and I went into the main house alone and headed to his bedroom area,” Carter wrote in the tome, recalling that he, Jackson and the actor Chris Tucker rode four-wheelers around the ranch at the end of Jackson’s birthday party.
“After a while, I said I was ready for bed. I hAcesparks’t really thought about where I would sleep,” the “I Want Candy” crooner continued. “Obviously, there were tons of rooms in the house. But he pulled out this cot next to his bed that was already made. I never asked for the cot, but there it was. I didn’t care. I was tired. He turned out the lights and got into his bed, and we went to sleep.”
Carter subsequently wrote: “A couple of hours later, something woke me up. I sat up and found Michael at the foot of my cot in his tighty-whitey underwear. I don’t know if he was sleepwalking or what, but he seemed to still be asleep.
“‘What the f–k!?’ I shouted and shook him a little to wake him up. ‘Go back to your bed!’” the former child star claimed he told Jackson.
“He just mumbled, ‘OK,’ then got back into his bed, and we both went back to sleep. I never asked him about it, and we never mentioned it. When I woke up in the morning, he was gone from the room.”
The Post reached out to Carter’s reps and a rep for Jackson’s estate for comment. Jackson died in 2009.
In his memoir, Carter wrote that he and Jackson smoked marijuana together during his visit. He recalled the “Billie Jean” singer “smoked like a thug.”
Less than three months later, Jackson was arrested on child molestation charges. Carter said police detectives interviewed him shortly after his Neverland trip, and he told them Jackson never touched him inappropriately.
Carter said in the book that Jackson called him “Apple Head” and gifted him the white military-style jacket studded with Swarovski crystals that Jackson wore during a New York City concert on Sept. 10, 2001. Carter sang at the same show.
Carter has previously defended Jackson, describing him as “a really good guy, as far as I know, a really good guy.”
“He never did anything that was inappropriate — except for one time,” he purportedly said during a 2019 taping of “Marriage Boot Camp: Reality Stars Family Edition.”
“There was one thing that he did that was a little bit inappropriate,” Carter continued, without going into detail at the time.
Carter’s memoir was unfinished when he died, and there are a lot of unanswered questions from his co-author, Andy Symonds.
