25-year-old Leslie Carter was found dead earlier this week

A police report has suggested that Leslie Carter died of an overdose of prescription drugs.

The body of the 25-year-old, who was sister to Backstreet Boys singer Nick and solo star Aaron Carter, was found next to prescription drugs Olanzapine, Cyclobenzaprine and Alprazolam. The drugs are used for schizophrenia, bipolar disorder and anxiety.

A full autopsy is now underway, after an initial report proved inconclusive, writes Rolling Stone. Former pop singer Leslie Carter recorded an unreleased album for DreamWorks in 1999 and her song ‘Like Wow!’ appeared on the soundtrack for Shrek. She was apparently battling prescription drug addiction before her death on Tuesday (January 31).

Last year her brother Aaron Carter said that Michael Jackson gave him drugs and alcohol when he was a teenager. Aaron told OK Magazine Australia: “I did things with him that nobody else did but I was also troubled about what he did to me”.

“He gave me wine,” he continued. “I mean, I could have refused, but I was 15. As for drugs? He gave me cocaine. I felt weird about that and other stuff.”
