Entertainment Tonight is reporting that the former couple is back on, with multiple sources telling the outlet the Boy Next Door star and her ex-beau celebrated the new year together in Las Vegas.
J.Lo was there for her "The Best Is Yet to Come" New Year's Eve concert special at Caesars Palace, although she showed no signs that the dancer was with her. There was no indication on his social media that he was in Vegas at all either.
Following their split in June, the Booty" crooner and Casper seemed to remain friends, even getting spotted out and about together not long afterwards.
Still, as J.Lo launched her memoir True Love last year, she said she felt like it was a good time for her to be single.
"I do what feels right in the moment and right now it feels good to just be on my own and have some 'I love Jennifer' time, which I haven't done a lot in my life," she continued. "My friends are constantly trying to set me up but I'm just not there right now. It's not something that's a priority."
It looks like she changed her mind.
