Kristen Bell, porn star. Okay, not really. KB (the voice of Gossip Girl) popped up in a new Funny Or Die video today, in which she plays an old-timey porn star in a dirty movie about the Supreme Court. Although the vid was written by fancy-pants playwright David Mamet, we don't actually think it's that funny. But Kristen's comic timing is killer as usual, and her old-fashioned lingerie is pretty. So enjoy. (It's not real porn so it's pretty much SFW.)
