Justin Chambers Checked Into Psych Ward

It's been a busy week over at UCLA Medical Center. Before Britney took over the hospital this morning, 'Grey's Anatomy' star Justin Chambers aka Dr. Alex Karev, checked himself in to the psych ward.

Chambers rep confirmed to TMZ that he checked in on Monday and checked out yesterday.

The rep said he was "exhausted and suffers from a sleeping disorder. He went in voluntarily to get some help."

Wish you well Dr. Karev!
