ET brought you the news about Kate Walsh's divorce on Thursday, and we caught up with her former "Grey's Anatomy" co-star Eric Dane at the 'Marley & Me' premiere to hear his thoughts on the split.

"That's terrible," Eric says about the news. "No I haven't seen her. I've got to call her. Thanks for reminding me that I need to call her and say… that's terrible."

ET's Thea Andrews talked to McSteamy about recent rumors that T.R. Knight may be leaving the show.

"Not that I know of," Eric says about his co-star leaving the cast. "I was with him yesterday working, so I don't know."
