No wonder she snagged the part of Fat Amy in Pitch Perfect. Not only is Rebel Wilson comedic gold in basically every movie she touches — have you seenBridesmaids?! — but she’s also a terrific performer. As in, singing performer. On The Tonight Show with Jay Leno, Reb showed off her vocal chops from her “breast voice” (her words, not ours), and put on a totally entertaining, impromptu routine to Lady Gaga‘s “Edge of Glory,” which was the song she had to sing during her audition video for Pitch. Watch the magic above!
