What do you do after you get a ridiculously huge engagement ring? Silly question. You flaunt it! And that's what Kristin Cavallari did yesterday in LA. The former star of "The Hills" got engaged to Chicago Bears quarterback Jay Cutler over the Easter weekend, after he reportedly surprised her with a trip to Cabo San Lucas, Mexico. The ring is said to be 5.2 carats. Hey, if things don't work out, she can always pawn the ring. Just sayin'.
