Check out Gaga taking a tumble from her piano as she sings 'You and I' on her Monster Ball tour.
It happened on the 10th April 2011 in Houston.
But Monsters need not worry -she wasn't injured and if you watch the video below you'll think it was all part of the act as Gaga gets straight back up and continues performing as if nothing ever happened.
So let this be a lesson to you - don't rock out at home, while singing, playing the air guitar and balancing on a piano in stiletto boots.
