Lady Gaga and fan got real close during her Las Vegas show on Thursday evening. The “Born This Way” star invited “Jack” on stage and jumped into his arms, but Jack lost his footing and fell off the stage with Gaga in tow. "We legitimately thought she was dead," an audience member wrote on Reddit. Gaga, being the true professional, got back up and performed flawless choreography to her hit, “Bad Romance.” Jack, on the other hand, was in tears and wasn’t okay after the fall. Gaga consoled him saying, "Don't worry, everything's fine. It's not your fault," she said, adding: "Could you promise me something? Could you forgive yourself right now for what just happened?" What was the worst fall you’ve ever had?
