I'm not quite sure why Lindsay Lohan chose to pose for this photo in a bikini at Jeremy Piven's birthday party. But I'm not complaining either. Anytime you can get A-list celebs to put on bikinis for your birthday you're doing well. Especially considering the party was black tie. Ok maybe that wasn't the case, I guess Lindsay Lohan could be wearing a bikini because there was a pool or something, but I really don't like logic, so I'm sticking will the black tie thing cause it makes this photo all the more interesting.
