Lady Gaga took a monster of a fall during her concert in Houston on Sunday, but the stumble didn't slow her down at all. While performing her song "You and I," Gaga was standing with one foot on the keys of her blazing piano and another foot on the piano's bench when she suddenly lost her balance and the bench toppled over, sending Gaga tumbling down onto her back. The 25-year-old managed to hold on to her mic, and crawled out from underneath the piano still singing. One concertgoer, who videotaped the fall, told the Daily Mail that she was "really high up and it looked really bad. I only just managed to keep the video steady. The crowd all saw it and I don't think anyone would have minded if she'd walked off the stage to get checked out by medics. But she was a real professional and jumped back up on stage to finish her set in front of the fans. It was really amazing to see." Source: CNN
