During Lady Gaga's "Enigma" residency in Las Vegas that kicked off last December, her "Star is Born" co-star Bradley Cooper made a surprise appearance.
In a video captured from the Saturday night cameo, the Philadelphia native joined Gaga onstage for an emotional performance of "Shallow" from the recent film.

It appears that Cooper was just in the audience to see "Enigma" when Gaga pulled him onstage to do the song. He started off the duet — while having his very first "in-ear" experience, thank you — and then Gaga took over on piano for Ally's part of the duet. The crowd, understandably, was beside themselves with joy.
Fans posted the videos to YouTube Saturday night. You can see Gaga get pretty emotional when he starts off the song. It's a very sweet moment between the two stars. You're welcome.
Cooper's "A Star Is Born" received eight total Oscar nominations, however he somehow got snubbed in the Best Directing category. Gaga received an Oscar nomination for her role as Ally in the film and "Shallow" received a nomination for Best Original Song.
