Bradley Cooper made a guest appearance at Lady Gaga’s Las Vegas residency on Saturday night to perform their A Star Is Born duet “Shallow” for the first time together live.
“So a really good friend of mine… I don’t know if you know him but his name is Bradley,” Gaga told fans while sitting at the piano onstage as the opening chords of the song played.
“He made that movie, umm, A Star Is Born. So I’m gonna be a little chance-y… Yo Bradley, you wanna come up and do this one?”
Cooper then joined Gaga on the stage, where he experienced some in-ear monitor problems and joked that his character Jackson Maine "never used these.”
It’s believed the duo will perform the song again at the Oscars on February 24.
