Shallow from Lady Gaga & Bradley Cooper's A Star Is Born is one of the most unexpected hits of the past year and it just keeps getting bigger.
It's won a Golden Globe and been nominated for an Oscar and Grammys. Now, the pair have finally taken to the stage together to perform it live.
Gaga was performing her Enigma show in Las Vegas when she was joined on stage by Cooper for the encore Shallow.
Ally and Jack belted it out just like they did multiple times in A Star Is Born and we've just fallen a little bit more in love.
