Lady Gaga takes a tumble! The singer fell flat on her back in front of thousands of fans during her Houston, Texas concert last night. Gaga was supposed to jump off her burning piano onto a stool, but instead, kicked the stool further away and fell to the stage ground. Ever the professional, she didn’t miss a beat! The popstar continued to sing her tune and proceeded to crawl from underneath the piano. Gotta love Gaga huh?
