Britney Spears almost had celebrity company in the psychiatric ward at UCLA Medical Center - Grey's Anatomy star Justin Chambers was also a patient this week. In a weird coincidence, the actor, who plays Dr. Alex Karev in the medical drama, checked himself in at the beginning of the week.

Chambers' representative has confirmed the star checked in on Monday and checked out hours before Spears was brought in for a 72-hour psychiatric hold.

The insider tells TMZ.com, father-of-five Chambers was "exhausted and suffers from a sleeping disorder and went in voluntarily to get some help".

It is reported Chambers was on the same ward where Spears is currently being treated.
