Thursday night, the 42-year-old invited millions to witness the chemistry she shares with Casper Smart, 25, during a performance of her latest single, Dance Again.
J-Lo fans will already know that the video for the upbeat tune features the couple getting hot and heavy, and the lyrics profess the mother-of-two’s love for Casper.
Nevertheless, few were expecting the judge to hijack the search for young talent to flaunt her relationship, again.
But, after taking the stage in a sequin covered bodice and a pair of black tights, Lopez headed a dance ensemble before Casper pulled away from the rest of the backing troupe to perform alone with the superstar.
They then engaged in an x-rated paso doble, which saw Casper grab his girlfriend’s buttocks as they twisted and turned around each other in paroxysms of ecstasy.

At the end of the routine, Casper even had the temerity to pick confetti out of J-Lo's hair after the performance ended in a flurry of ticker tape.
It was an obvious sign of familiarity, if not ownership from the youngster who has found himself swiftly promoted from dancer to choreographer.
Looking slightly flushed, she told the audience: "He’s so cute!"
