What's In The Water????

Justin Chambers checked in to the UCLA psych ward this week.

The Grey’s Anatomy hottie checked right back out of Britney‘s temporary home on Wednesday.

The actor’s publicist says he went in voluntarily because he is “exhausted and suffers from a sleeping disorder.”

Chambers is the father of five.

That could do it to you!

We hope Justin’s truly better.

Sleep is so important pees. We (all) gotta make sure we get enough of it!
