Brad Diaz, the paparazzo who on Sunday was pinged by a BB pellet while staked outside a Malibu baby shower Britney Spears was attending, is reportedly suing the pregnant pop star, claiming that the projectile may have come from her bodyguards.

It's not funny." You wanna see funny? Look at the final ratings for Britney & Kevin: Chaotic. Now that's funny.
