Hundreds of lucky fans were treated to Bradley Cooper and Lady Gaga singing "Shallow" together live for the first time.Bradley, Gaga's "A Star Is Born" co-star, attended Gaga's "Enigma" show on Saturday night.Gaga had to convince a very reluctant Bradley to get on the stage by saying, "So a really good friend of mine 맥스카지노� I don맥스카지노�t know if you know him, but his name is Bradley. He made that movie, umm, 'A Star Is Born.' So I맥스카지노�m going to be a little chance-y 맥스카지노� Yo Bradley, you wanna come up and do this one?맥스카지노�Of course, Bradley couldn't say no to Gaga or the screaming fans, so he very cutely performed the song with her, sitting on the piano stool with her at one point, and also riling up the crowd for Gaga's big singing moments. They also had a very sweet moment at the end, embracing each other lovingly.And honestly, they should just win an Oscar for best friends from a nominated movie because clearly, their love is very real.
