Grey's Anatomy Star and Britney in the Same Psych Ward

OK! has learned that actor Justin Chambers (who plays doctor Alex Karev on ABC's hit Grey's Anatomy) paid a visit to the same psych ward where Britney Spears is being held right now.

According to TMZ, the actor admitted himself voluntarily to UCLA Medical Center on Monday and checked out on Wednesday.

A rep for the actor says Chambers — who is a married father of five — was "exhausted and suffers from a sleeping disorder. He went in voluntarily to get some help."
