Kate Upton's twitpics are the stuff of legend. If there's ever been a model who's used Twitter to her advantage, it's Kate. To wit, she's even started incorporating sponsors into her act. Like Sobe Lifewater, which she collaborated with in a twitter contest that would see a lucky fan win one of her sexy twitpics autographed by Kate herself. The picture? Why it was Kate holding a bottle of Sobe Lifewater to her pretty little lips, of course.
