DENIES Affair w/ Singer
The guy at the center of the affair rumors is telenovela star William Levy -- aka the Cuban Brad Pitt -- who recently separated from his wife AFTER shooting the music video (see below) with Lopez.
But Levy's rep tells TMZ William and J.Lo are NOT an item ... saying, "The only relationship there was or is, is a professional relationship. That’s all there’s ever been.”
J.Lo and her husband Marc Anthony released a statement on Friday saying they are ending their marriage.
