Justin's Been A Bad Boy

Looks like the troubles for Grey's Anatomy star Justin Chambers aren't over ...

The young father-of-five has an admitted "sleep disorder" which landed him in the UCLA Medical Center psych ward at the same time Britney was there in January.

But now the Star is reporting that Justin apparently went on a bender in Palm Springs 26 days after he was released from the hospital.

The mag reports a source saw the star at the Village Pub in the desert town and said his demeanor there:

"Justin was drunk because he kept passing out at his table .. He was acting as if he was on drugs, like some kind of downers. his eyes were glazed over. He slurred his words and staggered when he tried to walk."

The source reportedly told the Star that at one point the Grey's star shouted out:

"I am a father of five kids! I am a damn good father! Leave me alone!"

He was without his wife Keisha and was reportedly hitting on a waitress at the bar.

Too sad! We hope Justin gets some help for his own sake and for the sake of his family!
