Jennifer Lopez's 2009 AMA Tumble

She’s the consummate performer, and last night (November 22) Jennifer Lopez took the stage at the 2009 American Music Awards for an electrifying performance.

The “Waiting for Tonight” songstress dressed in a sexy black and gold getup as she wowed the crowd at the Nokia Theatre LA Live, singing her latest single “Louboutins.”

Unfortunately, J. Lo lost her footing as she jumped off a human pyramid of male dancers and ended up on her backside.

But she got right up, and will.i.am told press how impressed he was with Lopez’s recovery. "That shows she's a true entertainer and devoted. She came out of it and still rocked it. It doesn't matter how you fall - just how you get up. She got up."
