The cast of Grey's Anatomy is not at war. 

That's according to Justin Chambers, who plays the hunky, moody Dr. Alex Karev on the hit medical drama. Chambers was spotted out at the Xbox 360 Gears of War launch in Los Angeles earlier this week and Life & Style Weekly caught up with him briefly.

Chambers was, of course, asked about the recent conflict on set, but was quick to downplay it, calling the fight between co-stars Isaiah Washington and Patrick Dempsey on October 9 nothing but "water under the bridge" by now.

"It happened awhile ago. Like any workplace, we spend a lot of time together. Sometimes we get into arguments and sometimes we don’t," said Chambers, a former model and father of five.

"We’re a pretty close-knit family. Everything’s smooth now. Everything is fine. We’re all getting along fine."

As for another fellow cast member, T.R. Knight, whose decision to come out of the closet sparked even more discussion this past week, Chambers simply says, "It’s all cool."

"T.R. is a great guy. He felt the need to explain that. It’s his personal life, and God bless him."
