I would say Alexis Bledel on the strength of that second pic, wins the contest. And that's saying something considering Keri Russell's derierre.
Speaking of that second pic, check out the two scuzzy guys getting her autograph. Anyone seriously think they're her two biggest fans. Those are likely autograph hunters who troll for signatures then sell them on eBay or wherever they can sell them for the highest price. They're exactly the reason why a lot of celebs don't sign autographs.
