Paula Abdul Falls Off The Stage At The Hard Rock

We are amazed that this doesn't happen more often. This is fan shot video of Paula Abdul falling off the stage while performing in Biloxi, Mississippi.  She was okay and quickly returned tot he stage.  The most shocking thing to us, is the fact that she keeps singing perfectly even though she fell off the stage.  Almost as if she wasn't singing live!  AMAZING!  If you don't have to worry about singing the songs (since she's singing to a recording) you would think she'd have more focus to see where the stage ends.  We are just happy that she's okay, but we are more shocked that people pay money to see "stars" lip sync to music.  What happened to actual performers?
