Was J-Lo Cheating?

Rumors are flying about the Jennifer Lopez-Mark Anthony split. Two online sites report one of them was cheating.

HollywoodLife and Bossip are reporting that Lopez might have had a fling with Cuban model William Levy.  He's the guy who played her sweetheart in the “I’m Into You” video.  In fact, Levy has split from his wife since shooting the video.  But Lopez's rep says this is just not true.....saying the accusations are 100% inaccurate.
