Jennifer Lopez picked up the prize for Favorite Latin Music Artist Sunday night at the American Music Awards.

Lopez also performed her sexy single "Papi" and joined fellow Latin Music Artist nominee Pitbull for her hit single "On The Floor."

Meanwhile, her soon-to-be ex, Marc Anthony, also hit the stage with collaborator Pitbull to perform "Rain Over Me."

Despite sharing the same space and sharing hit producer Pitbull, J Lo and Marc Anthony seemed to successfully avoid each other ... including Lopez's avoidance of Marc's name in her acceptance speech.

She thanked her family and her long-time manager Benny Medina, but even as she struggled to find her next words, the name "Marc," never popped into her mind ... or at least not out of her mouth!
