Did JLo Cheat on Casper With Marc Anthony?

JLo was seen entering Marc Anthony's hotel in NYC wearing a leopard jacket and short skirt and sexy thigh high black boots. No kids in tow. Not even her bf Casper. hahahahaha 2.5 hrs later, Marc was seen exiting the hotel without the kids and without JLo. She was still in the room probably taking a shower. hahaha Some time later, JLo departs the hotel, again sans kids. So what do you think? Did they or didn't they?
