On Wednesday night, the 25th, U2 performed at The Sphere in Las Vegas and invited Lady Gaga on stage to sing a few songs.
The pop diva, who recently lent her vocals to the new Rolling Stones , was introduced by Bono Vox and sang "All I Want Is You" and the classic "I Still Haven't Found What I'm Looking For".
In addition to U2's own songs, Gaga also performed a duet with Bono Vox, singing the hit "Shallow." The song was part of the soundtrack for the film A Star Is Born (2018), starring the singer herself, and won an Oscar, a Golden Globe, and two Grammys.
