Beyonce falls face-first down flight of stairs

Beyonce Knowles made a dramatic misstep and fell face-first down a flight of stairs during a concert. But as she is the stage professional, she got up and went on like 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, Florida, when she tripped and stumbled down several stairs.

Knowles quickly regained her footing, reclaimed her microphone and went on with the show.

A spokeswoman for the singer did not immediately return a phone call from The Associated Press on Thursday.

Amateur videos of the tumble had nearly 900,000 hits on the YouTube.com Web site Thursday morning. Posting of the videos began Wednesday.
