Justin Chambers' Psych Ward Visit!

Grey's Anatomy star Justin Chambers (aka Dr. Alex Karev) was briefly treated at UCLA Medical Center's psych ward this week. Chambers checked in on Monday and out on Wednesday — right before Britney Spears arrived for treatment early Thursday morning.

Chambers' rep told TMZ the actor was "exhausted and suffers from a sleeping disorder. He went in voluntarily to get some help."
