"Ring the Alaaaaa...." plop!

"Beyonce stumbles during Orlando show
NEW YORK - Beyonce Knowles made a dramatic misstep when she fell face-first down a flight of stairs during a concert. Ever the stage professional, she got right up and continued her performance as if nothing had happened.

The 25-year-old singer — flipping her hair dramatically and wearing a long red trench coat and high heels — was performing her song "Ring the Alarm" during a concert Tuesday in Orlando, Fla., when she tripped and stumbled down several stairs.
Knowles quickly regained her footing, reclaimed her microphone and went on with the show."
