Lady GaGa's antics have got everybody taking it to the next level, including her recent partner in crime Beyoncé. Hot on the heels of her fierce collabs with GaGa, B is again staking her claim as 'hottest chick in the game' by stage-diving into a crowd at her London show during a performance of 'Halo.' The video quality is a little bit terrible -- but hey, it's an illegally filmed cell phone video from an arena show. It still gets the point across. So who's buying me Beyoncé tickets for Christmas?
