In I Love You, Beth Cooper, an upcoming film every guy must see to retain his manhood, Hayden Panettiere is naked. Yes, naked. It's unclear how much you get to see in the movie, but from these awesome photos from her visit to Letterman, anything is better than nothing. Seriously, I'd just take some more bare ankles... then if you want to throw in a boob or two as well, I'm not going to argue.
