Interesting!
Of course, "sexier" is in the eye of the beholder, whereas "stronger" is more of a value judgment based on a close scrutiny of thousands of Internet photos (and possibly stories...which are accurate, eyewitness, accounts of actual battles waged...although I COULD be wrong about that!)
I can't argue with anyone's vote on "sexier" ... or on "stronger" either, but I WISH the question had been asked, "Who'd win the fight?" (since "fights" is sorta the excuse for having this thread) and while I'd love to vote Lawrence for that, given Kate's larger size (overall, including weight and height) I think Upton would get my vote.
(see how I 'bumped' this back up while not appearing to want that to be the main effect?)
