New York celebrity disc jockey DJ AM has been found dead.
DJ AM, a 36-year-old whose real name was Adam Goldstein, was found in a Manhattan apartment.
The death comes a year after Goldstein survived a plane crash that killed four other people in South Carolina.
His representative has confirmed: "Adam 'DJ AM' Goldstein was found deceased this afternoon in his New York City apartment. The circumstances surrounding his death are unclear. Out of respect for his family and loved ones, please respect their privacy at this time."
The star - who once dated Nicole Richie - had battled drug addictions in the past, and it has been reported prescription medications were found at his apartment.
New York Police Department (NYPD) Deputy Commissioner Paul Browne has said there was no sign of foul play.
Another police source claims the musician was not wearing a shirt when he was discovered, and was face down in bed.
It has been claimed DJ AM was upset after splitting from his girlfriend, model Hayley Wood recently.
A source said: "She ended it, and he didn't want it to end. The breakup hurt him. He hadn't been in a good place lately. For the past week, he wasn't really around, he was keeping to himself, and he was blowing people off."
On Thursday, he wrote on his Twitter page; "New york, new york. Big city of dreams, but everything in new york ain't always what it seems."
DJ AM was involved in a plane crash with Blink 182's Travis Barker last year, which saw several people die.
Last month, he admitted: "There's no reason why I lived and they didn't. It's something that I struggle with every day, you know, kind of wondering. But I've just realised I'm never really going to know.
I'm alive, and I'm here, and I have another chance. So I have to do something better with my life this time."
Fellow DJ Jon 'iamxl' Hamlin expressed his shock at the news.
"I was lucky to have played with him a few times, he was just a really genuine guy," said Hamlin.
"He was one of the most famous DJs in America, had millions in the bank, gigs all over the country, yet was still really humble and down to earth. He just loved music and loved making people happy.
"It was a real shame and real tragic loss. Just totally tragic."
He has previously admitted he came close to committing suicide in the past, claiming he nearly ended his life in 1997 when he was 24.
He explained: "I put the gun in my mouth and I pulled the trigger, and it jammed. And I remember sitting there thinking: 'You know, I can't even kill myself.'
