Justin Chambers Knows his Limits

Grey's Anatomy star Justin Chambers checked into a psychiatric ward this week.

The 37-year-old actor - who plays Dr. Alex Karev on Grey's Anatomy - has been suffering from a "sleeping disorder" and voluntarily admitted himself to Los Angeles' UCLA Medical Center on Monday (28.01.08), before leaving the facility two days later.

Couldn't he just take a vacation?

The pictures here are from work he did as a Calvin Klein model. Justin has been married since 1993 and has 5 children. He is pictured above with one of his twin daughters.
