Fans can reportedly look forward to another side of Lady Gaga when she teams up with Metallica for the 59th Grammy Awards show on Sunday night (Feb. 12). "I was at Bradley's house with [Metallica drummer] Lars [Ulrich] and we were just hanging out," the singer shared. "He's amazing. I went to see them live, I saw them recently and we were watching the show, those guys play better than they've played in their whole lives."
