U2 surprised fans at their 'U2:UV Achtung Baby Live At Sphere’ show on Wednesday night by bringing out Lady Gaga to duet on her mega-hit 'Shallow'.
Bono and Lady Gaga also duetted on U2's 1989 love song 'All I Want is You'.
The 37-year-old pop superstar had recently checked out the legendary Irish rock group's show at the new state-of-the-art, multi-billion-dollar immersive MSG Sphere at the Venetian with her boyfriend Michael Polansky.
She returned weeks later, this time duetting with Bono and The Edge on her 2018 hit from her blockbuster movie 'A Star Is Born'.
The Grammy winner previously duetted with U2 on 'Ordinary Love' during the band's 'iNNOCENCE + eXPERIENCE' tour at Madison Square Garden in 2015.
Gaga’s latest live duet comes days after she jumped onstage with The Rolling Stones to perform their new song 'Sweet Sounds Of Heaven' at Racket NYC in Manhattan.
Meanwhile, U2 have just extended their residency due to "unprecedented demand".
Bono and co became the first act to perform at The Sphere on September 29th.
The Sin City stint was due to end on December 16th, but it's proved so popular, that they've added an additional 11 concerts between January 26th and February 18th.
The Irish band have been performing their 1991 album ‘Achtung Baby’ in full alongside some fan-favourites at the concerts at the new high-tech.
The cutting-edge venue sees the crowd placed in a "360-degree sonic spectrum".
Those lucky enough to get tickets will experience a concert like no other, due to the venue being built for cinema and performance, not sport.
Speaking to Zane Lowe on Apple Music 1, frontman Bono explained: “Most music, over playing a theatre, most music venues are sports venues. They’re stadiums, they’re arenas. They’re built for sports.
"They’re not built for music, they’re not built for art. So this building was built for immersive experiences in cinema and performance. It was not built for [sports], you can’t come here and see an ice hockey game.
“There are no speakers. The entire building is a speaker. So wherever you are, you have perfect sound is the plan."
Meanwhile The Edge said: “There’s nothing else like it in the world and won’t be for many, many years.”
He went on: “So what this has been designed to achieve is completely immersive sound. So you’ve got the main array of speakers is above our heads, but throughout the entire building are speakers that are focused so that you have the capability of placing the audience inside a whole 360-degree sonic spectrum.”
The musician also hailed the visuals as "ground-breaking".
