looked stunning at the premiere of the movie Marley and Me. Her co-star Owen Wilson
also seemed impressed by her beauty and they looked like a super cute couple. Wonder if Jen's boyfriend John Mayer
, who also attended the premiere, got jealous? We are disappointed at Jennifer best friend, Courteney Cox
, who didn't even have a dress on! The Grey's Anatomy
stars T.R. Knight
and Katherine Heigl
weren't better but at least they had some red accessories to get in Christmas spirit! Kristin Cavallari
on the other hand really sparkled!
