Lady Gaga joined U2 as a special guest on stage at the Sphere in Las Vegas.

The singer took to the brand new stage to perform a rendition of Shallow, her song from A Star Is Born with the Irish rockers.

Gaga and Bono also performed two U2 songs together kicking off with All I Want Is You and an emotive duet of I Still Haven’t Found What I’m Looking For.

Fans went wild at the surprise appearance during their first run of shows at the €3 billion venue.

Fresh after rocking with the Rolling Stones last week, Gaga looked like she was part of the band as she took to the stage in a leather jacket and sunglasses.

The superstar’s appearance followed on the heels of her recent performance with the Rolling Stones at New York City club Racket last week.

She joined the band for Sweet Sounds of Heaven from the Rolling Stones’ recent LP, Hackney Diamonds.

It also comes as Gaga finished up her own Vegas shows earlier this month. She wrapped up an extension of her long-running Jazz & Piano residency at Dolby Live in Park MGM.

This isn’t Gaga’s first time joining the iconic Irish band, having previously performed with U2 at New York’s Madison Square Garden in 2015 when she joined them to sing Ordinary Love during their Innocence + Experience Tour. The tour saw numerous special guests pop by the shows.

The band recently announced that they will now play an extra 11 shows in January and February of 2024 during their acclaimed U2:UV Achtung Baby Live At Sphere residency.
