Jennifer Lopez and Pitbull ‘Live It Up’ at 2013 Billboard Music Awards

Jennifer Lopez's Billboard Music Awards performance opened with Matrix-inspired numbers going across a screen and the singer's voice reciting a manifesto about living life to the fullest.

Then rapper Pitbull appeared wearing yellow pants and warmed up the crowd before Lopez came center stage, rocking all red.

With feathers and thigh-high red boots to accessorize her leotard, the singer got busy to the electro-pop track, proving she still has moves at 43.

J. Lo's choreography included sliding down poles and climbing up barricades, while her background dancers, dressed in gray suits and bow ties, filled up the stage with fancy moves.

The crowd hopped along as she commanded them to 'Live It Up' for the new fist-pump summer anthem.
