Which one is not like the others

Jason's hobby/fun site CelebSafari was featured as Yahoo's Dec. 21 pick of the day (you'll have to scroll down to it; no permalinks or anchors). One line in the description reads "Can you spot the supermodel in this trio?" and links to this photo taken at Sundance last year.

I'll give you a hint: I'm not the supermodel. You might think that caption would sting a bit, but I got to hang out with a supermodel, so I'm really not too sore over the whole thing.
