Madonna and Britney; Photo - Splash

Britney Spears is making good on her mission to kiss every single at least semi-famous woman when the cameras on her from now till doomsday. There was Halle Berry on Saturday Night Live last week, and now there's Madonna (again!). In the video for Britney's "Me Against the Music," she goes head to head with Madge. Britney says, "The video is more sensual than I’m used to and I’m touching on subjects I would not normally touch on." What, pap smears?
