Lady Gaga and Bradley Cooper starred together in the romantic musical, A Star Is Born. The movie went on to become a hit, managing to make moviegoers cry rivers. The songs of the movie, especially one titled Shallow, went on to top the music charts for weeks. Too bad for the fans at Lady Gaga's Enigma residency concert in Las Vegas, because they were in for an emotional surprise. At one point during her performance, Lady Gaga pulled up Bradley on stage, who was seated amongst the audience. And the two went on to sing Shallow. Maybe they felt their fans needed a good cry?

Videos of the performance are viral on Instagram and YouTube. “So a really good friend of mine… I don’t know if you know him, but his name is Bradley. He made that movie, umm, A Star Is Born,” she told the audience, inviting the man of everyone's dreams on stage.

A very reluctant Bradley gives in to the charm of Lady Gaga's thousands of chanting fans. He joins his co-star on stage and after a brief prep, lets out those sweet sweet vocals. Lady Gaga Stuns in Emotional Number from 'A Star Is Born'.
