Just when we thought Bradley Cooper and Lady Gaga couldn’t get any cuter, the pair have proved us wrong with a surprise performance.

Bradley joined Gaga on stage during the latest show of her Las Vegas residency on Saturday night.

The 44-year-old actor, who starred alongside Gaga in the critically acclaimed movie A Star Is Born, joined the chart-topping singer for her show in Sin City, where they performed a rendition of the song Shallow, which features in the film.

Gaga, 32,  who played a young singer in A Star Is Born, is currently in the midst of a residency at the MGM Park Theater, where she started her run of shows in December.

A Star Is Born has opened up a new career path in acting for the singer, who won the Best Actress gong at the recent Critics’ Choice Awards.

Bradley, who also directed the film, recently opened up about his decision to cast Gaga in the movie.

“I happened to be at a cancer fundraiser and she was singing La Vie en rose and I was blown away. I’d never heard her sing live before,” he told Yahoo Lifestyle of the moment he knew Lady Gaga had to be part of his film.

“So ideas started swirling around in my head about her potentially playing a character for this love story. Then I met with her a couple of days later and right away we had a great chemistry,” he continued.

“I just felt so easy and relaxed and we sang together and it felt like that worked. That was the beginning of it and then there was no movie without her.”
