I was looking at youtube, to see if I could find another video to add to my lady Gaga hub, and I found a video of her singing "Show Me Your Teeth."
She had on these aweful high heeled shoes. Well, she was doing a dance to the song, and fell right on her ass on stage. You could tell it wasn't lip singing, because you could swear she says shit as she is falling! But, she gets right up and keeps on singing.
A word of advice! Ditch the hooker boots!
