Lady Gaga Sings Background Vocals On U2's 'Songs of Experience' Album

Little Monsters listening to U2's newly-released album Songs of Experience might have recognized a very familiar voice on one of the tracks. While never officially announced, Lady Gaga has provided background vocals for track six on the new CD called "Summer of Love."

The song is about the refugee crisis in Syria and has been called one of the album's highlights. "I've been thinking about the West Coast / Not the one that everyone knows / In the rubble of Aleppo/ Flowers blooming in the shadows / For a summer of love," the band's frontman, Bono, sings.
