Popsugar Entertainment A Star Is Born Bradley Cooper and Lady Gaga Sing "Shallow" Jan. 2019 Video Bradley Cooper and Lady Gaga Performed "Shallow" Live, and I'm a Full-Fledged Mess Now 28 January 2019 by Karenna Meredith First Published: 27 January 2019 Be still my A Star Is Born-loving heart. Bradley Cooper and Lady Gaga finally performed "Shallow" for a lucky Las Vegas audience during Gaga's Enigma residency on Jan. 26, and it's every bit as magical live. While Gaga usually closes her Vegas show with the Oscar-nominated song, Cooper's appearance was an exciting surprise for fans. He started off the emotional serenade as Gaga knelt by his legs and listened intently. She appeared to tear up after his verse, and quickly moved to the piano to belt out her own part, eventually finishing the song with Cooper sitting at her side. It's plain to see Gaga and Cooper share a tight-knit bond. The duo have frequently raved about each other in acceptance speeches and interviews. Perhaps this passionate and energetic duet was just a trial run before their much-anticipated Oscars performance? Watch a full video of the song above, and then dive in fully by checking out other angles of their duet below.
