Jennifer Lopez Grinds and off stage with 24 year old Beau

Jennifer Lopez have tongues wagging both on and off the stage at the American Music Awards last night. The singer danced provocatively in a flesh-colored bodysuit for a performance, but gave her 24-year-old boytoy a private lap dance at an after-party, reports say.

Lopez start the night demurely enough, singing and dancing, flowing dress on the stage of the Nokia Theatre in Los Angeles. But soon, the "American Idol" judge stopped with a naughty smile and ripped off her dress, revealing a rhinestone-encrusted body suit underneath. It was a strikingly similar ensemble to the one Britney Spears donned for her MTV Video Music Awards performance of "Oops, I Did It Again" in 2000 after stripping off a tuxedo.

As Lopez sing her song "Papi," the triple threat was covered by a small army of male backup dancers, who pulled yet another layer of beading off her bodysuit. When rapper Pitbull came on stage, Lopez walked seductively toward him, leaning forward on a cane and rubbing her posterior against his crotch.
