Katherine Heigl might hate her on-screen relationship with George O'Malley, but in real life the Grey's Anatomy co-stars are total BFF's. T.R. Knight recently told US Magazine that he's going to be a bridesman in Katherine's wedding to singer Josh Kelley on December 23rd.
"I'm standing up there and all," Knight told Us. "So I have to go and get the tux. And I am still deciding on a gift!"
Don't worry, T.R., I'm always the bridesmaid too! Your day will come soon enough (or at least that's what my mother keeps telling me).
