Did DJ AM kill himself? That’s unknown — for now.

The New York City Medical Examiner’s Office disputes reports that suicide has been ruled out in Friday’s death of the celebrity spinner.

An autopsy on Saturday was inconclusive and investigators are relying on toxicology tests to help figure out the cause of death for the 36-year-old DJ, whose real name was Adam Goldstein. They may take several weeks.

Another theory is an accidental overdose. A small bag of crack was found in his apartment, along with a crack pipe and prescription pills.

Sources tell E! News that AM, a recovering addict, had begun taking anti-anxiety meds after surviving last year’s plane crash with rocker Travis Barker.

BYE, BYE TV

Audrina Patridge is moving on from The Hills.

“It feels like I’m graduating,” the actress told UsWeekly.com about quitting the popular MTV show. “I’m taking the next step and growing up and maturing and moving on in my life.”

Guess Patridge thinks she’ll find stardom in movies. Next up: a killfest about a college prank gone awry — Sorority Row — with a bloated looking Carrie Fisher and Hollywood spawn Rumer Willis, out Sept. 11. Its tag line: “Theta Pi must die.”

BAD MEMORY

For such a young guy, Chris Brown looks to be suffering a touch of dementia.

In the singer’s first public interview since his

arrest and plea for assaulting Rihanna, Brown tells Larry King that he has no recollection of what happened Feb. 8 and that he can’t believe what he did.

“When I hear about the police reports, I don’t know what to think,” Brown says during the interview, which will air on CNN Wednesday. “That’s not who I am as a person. It’s like crazy to me.”

That’s interesting, because according to documents unsealed following Brown’s sentencing, he was reportedly in two other domestic violence incidents with Rihanna, but no charges were filed because both instances occurred overseas.
