She may never be as famous as her movie-star siblings River and Joaquin, but who would you rather see naked--her marquee brothers or neo-hippie ingénue Summer Phoenix? The intense and natural brunette beauty has been knocking audiences dead since she guest starred on Murder, She Wrote at the age of six. A child of Christian missionaries, Summer shared her blessed boobs, buns, and bush in eSTheR KaHN (2000). The game girl's motto must be, "If you're going to try something new, you might as well try it buck naked." Summer toned back to tits-only for her bare-top role in The Believer (2001). There's still plenty of time for Summer to let her clothes fall.
