Bradley Cooper and Lady Gaga have captured the hearts of the nation since they appeared in A Star Is Born together last year as Jackson and Ally. The beautiful story, which was a remake of the 1976 film starring Barbra Streisand and Kris Kristofferson, also had a stunning soundtrack performed by the pair.
Whilst many of the songs from the film have become hugely popular, the original song 'Shallow', written by Lady Gaga and Mark Ronson has become the song of the season, and even won Best Original Song at the Golden Globes.
And fans of the film and the song were given an absolute treat at Lady Gaga's residency show 'Enigma' in Las Vegas on Saturday night (26th Jan) when Bradley actually joined her on stage to perform.
Although the pair, of course, sang the song together for the film, this is the first time they've sang it live together, with Bradley joining Gaga on stage after being seated in the audience for the first part of the show.
Thankfully, there's a video online of the moment, and Gaga can be seen helping him prepare for the performance and even giving him ear buds, with Bradley joking that his character hadn't used them.
