Bradley Cooper joins Lady Gaga for surprise Las Vegas performance of 'Shallow' from A Star is Born

Gaga has been closing each night of her 'Enigma' Las Vegas residency with the hit song

Lady Gaga had a surprise for audience members at her Las Vegas show on Saturday night, when Bradley Cooper came out to perform their hit song “Shallow”.

The duo performed the Oscar-nominated track from the film A Star is Born during her Enigma show on 26 January.

Watch footage of the performance, below:

Lady Gaga is up for a Best Actress Oscar for her starring role in the movie, which was directed by Cooper. She has been performing “Shallow”, which is also nominated for four Grammy Awards (Song of the Year, Record of the Year, Best Pop Dup Performance and Best Song Written for Visual Media) as the closing number for her Las Vegas residency.

After Cooper joined Gaga onstage, the singer joked: “I even got you in-ears!” Cooper joked that he couldn’t “hear anything” and has ”never used” in-ears before. Gaga played the piano while Cooper sat alongside her.

Cooper was one of the shock snubs at this year’s Oscars, as many believed he was a dead cert for the Best Director category.

Responding to the other nominations for the film with a statement, he said: “Everyone who worked on this film truly risked putting themselves out there—in the hope that in doing so people will connect and feel something deep and personal—the way films have made me feel since I was a kid. When I got this opportunity I knew I had to risk it all because I may never get another chance—so to be here today in a place where people who have seen the film are talking about how it makes them feel, something deep—that simple human thing—that we need each other—and the Academy to recognize that this morning—I just am so grateful,” he said in a statement.

Gaga later told the Los Angeles Times. “Well, you know, you never know what’s going to happen. But at the end of the day, he knows that he’s the best director in my eyes, and in all of our eyes as his cast,” she said. “I know that he’s so happy that we’ve all been nominated and that the film was recognized and we all feel really, really beyond elated for the recognition.”
