Coining a new phrase, perhaps? Katherine Heigl’s “Grey’s Anatomy” co-star T.R. Knight will be a “bridesman” in Heigl’s upcoming wedding. And why not? Katherine and T.R. are good buddies, so it only makes sense that he would be involved in her big day.

T.R. Knight commented on his role as bridesman in Katherine Heigl’s wedding (to Josh Kelley), saying, “I’m standing up there and all. So I have to go and get the tux. And I am still deciding on a gift!”
