She's definitely going down in the books as making one of the greatest come-backs of all time!
J.Lo kilt it Sunday night at the American Music Awards with her medley performance.
First, she sang a slower, sentimental Until It Beats No More as she donned an ethereal gown.
Then, her wings flew off so she could pump some Papi into everyone.
But the real fun began when she stripped down to a sparkling nude suit a la Britney Spears. That's when she and Pitbull TORE IT UP On the Floor!
We're serious. We think this was the best performance of the night! U gotta watch it! Play it!!!
