Did Jennifer Lopez Catch Casper Smart Cheating?

Jennifer Lopez and Casper Smart reportedly split again in August, but what really happened?

A source told People that Casper allegedly cheated, saying, “She kicked him out because he cheated on her and he got caught. It happened two years ago, and he promised he would never do it again and once he did, she was done.”

The insider revealed that Casper has been trying to change Jennifer's mind, even getting some new ink. “He's been doing everything he can to get back together, working on himself and posting on his Instagram saying that 'Life is Good' and showing off his new leg tattoo that says 'You must embrace the darkness to see the light.'”

The source reiterated, “The truth is, he was cheating and now that it's over he's been begging to come back.”

Back in August, Jennifer, 47, and Casper, 29, sparked breakup rumors when he failed to accompany her to a Hamptons party. The insider pointed out, “He was kicked to the curb not because he did not attend a party with J.Lo, but because he was caught having parties of his own. No one has time for that, especially J.Lo."

"He says he's changed and that he is a new man, but recently, on a video shoot for Wisin in Mexico, he was posting videos with bikini-clad dancers and not acting like a guy trying to remedy old habits," the insider added.

Smart's rep emphasized that everything was “strictly work, nothing personal,” since Casper was serving as creative director for the video. His rep had "no further comment" on cheating rumors surrounding Casper.

In August, when split rumors swirled, another source told People, "It wasn't anything dramatic and they were on good terms – it just came to a natural end. They will remain friends and they see each other, but they are not together. It was very amiable.”

Last month, Lopez posted a cryptic Instagram pic of herself standing in front of graffiti, which read, “Protect Yo Heart.” She captioned, "@egt239 i think this is what you meant to post... Ha. #protectyourheart #shadesofblue #setlife.”
