Beyonce! The songstress hit a Grammy record for a female artist with her six awards, including Song of the Year for "Single Ladies (Put A Ring On It)" and Best Female Pop Vocal Performance. She also brought the house down with a rocking performance of "If I Were A Boy" and Alanis Morissette's "You Oughta Know." The night also proved memorable for Taylor Swift, who took home four Grammys including Album of the Year and shared the stage with rock legend Stevie Nicks.
Lady Gaga, who kicked the show off with a remarkable piano duet featuring a glitter-spectacled Elton John, won two Grammys for best dance recording and best electronic/dance album.
