Video: Lady Gaga Thrills on 'SNL'

Lady Gaga fought with Madonna, performed a fiery version of “Paparazzi,” and sent herself into orbit during a medley of “LoveGame,” “Bad Romance,” and “Poker Face” on “Saturday Night Live.” She capped her sensational night by donning her bubblicious Rolling Stone cover outfit for a skit with funnyman Andy Samberg.
