Drew Barrymore hit the streets of LA yesterday to protest the California Supreme Court's decision to uphold Proposition 8. She took the stage at a rally, saying, "I am who I am because of the people who influenced me growing up, and many of them were gay. No one has any right to tell anyone what makes a family. . . You choose your battles in this world. . . this is something that means everything to me." It's obviously a cause close to Drew's heart, and she was joined for the afternoon of activism by fellow celebs like Pete Wentz and Kelly Osbourne.
