'House' celebrates 100 episodes with a red-carpet, black T-shirt event

The cast and crew of "House" gathered in Los Angeles at STK to celebrate their upcoming 100th episode. The event was also a National Alliance on Mental Illness (NAMI) charity event, so the stars traded in their usual glamorous garb for black T-shirts.

The 100th episode of "House" airs Monday, Feb. 2, at 9 p.m. ET/PT on Fox.
