Stage Falls Hall of Fame Thousands Screaming Fans Selena Gomez

Gravity is the great equalizer, especially when you're performing on stage in front of thousands of screaming fans, and Selena Gomez is the latest celebrity to learn that lesson the hard way.

During a performance of "Slow Down," the 21-year-old pop star pogo-ed a little too close to the edge of a stage riser and tipped over the onto the lower level, letting out a yelp which, if fans weren't painfully aware already, definitely gave away giant lip-syncing component of her show. Gomez rallied back though and kept right no dancing with a big smile after she was helped back to her proper position.
