Aaron Carter

Aaron Carter says Michael Jackson gave him cocaine and alcohol when he was 15.

"Yes, he gave me wine. I mean, I could have refused, but I was 15," Carter tells the Australian edition of OK! "He gave me cocaine. I felt weird about that and other stuff. ... We spoke afterwards, hours and hours, on the phone. I admired Michael, but his behaviour bothered me a lot. Then my mother called the police."

Carter says he was "troubled" by what Jackson, who died two years ago, did and has never talked about it until now. "I miss Michael," the Dancing with the Stars alum says. "I have spent such incredible times with him. I did things with him that nobody else did."

Carter, 23, the younger brother of Nick Carter, entered rehab for "emotional and spiritual issues" in January.
