Jennifer Lopez and new toyboy get raunchy on stage - in front of her ex Marc Anthony

FLAUNTING her famous curves in a skintight glittery bodystocking, Jennifer Lopez showed off her toyboy Casper Smart to the world this weekend.

The Latin lovely, 42, delighted fans at the American Music Awards by dancing with tattooed Casper, 24, in her raunchy routine.

t’s been only five months since JLo’s seven-year marriage to Marc Anthony broke down and, amazingly, he was in the audience watching her rap with Pitbull and grind with her new lover.

After the show the American Idol judge and her handsome boy toy – who she’s been dating for a few weeks – headed for a not-so-private booth at the after-party where she treated him to a special lapdance before they headed off into the night.

What a performance.
