Lady Gaga Backstage A Cappella 'Born This Way'

Singer warms up backstage for HBO show

In this clip from Lady Gaga's Monster Ball: At Madison Square Garden special on HBO, the singer warms up with her backup vocalists backstage by performing an a cappella rendition of her hit "Born This Way." Gaga's enthusiasm for the song is impossible to mask – when she sings "I love my life/I love this record" halfway through, the proof is in her wide, genuine grin.
