According to TMZ, the duo was not shy about sharing a smooch when he stopped by "American Idol" Wednesday night, and they reportedly kissed out in the open for everyone to see (the kiss was even snapped by photogs).
The site later reported that the Boy Next Door and Casper never really split and the break-up they announced in June was a business move that helped J.Lo promote The Boy Next Door and play up rumors that she was hooking up with her co-star Ryan Guzman.
The move supposedly also worked for Casper, who was in the midst of shooting Street, a UFC fighter movie. Still, neither the dancer or J.Lo has confirmed they're back together (or that they never broke up).
Meanwhile, Casper was on hand at the actress-singer's Home premiere Sunday in Los Angeles, and responded to the buzz that they're dating again. "We got a lot of ties. We're very close," he said. "We're friends. We're very good friends." J.Lo also told the outlet she wasn't seeing anyone.
Very good friends who kiss? What do you think about all of this? Tell us in the comments!
