Lady Gaga surprised fans who attended her “Enigma” show at the Park Theater in Las Vegas on Saturday night with a special performance with her “A Star is Born” co-star, Bradley Cooper.

Cooper was in attendance at the show when Gaga announced she was bringing him on stage to sing her finale song.

“So a really good friend of mine. I don’t know if you know him but his name is Bradley. He made that movie, um, ‘A Star Is Born,’” Gaga said to the crowd. “So I’m gonna be a little chance-y. Yo Bradley, you wanna come up and do this one with me?”

Cooper came on stage and hugged Gaga who told him she had in-ear monitors for him to use which was new for him.

“Jackson never used these,” Cooper jokes. “I can’t hear anything.”
