Jennifer Lopez Broke Up with Casper Smart Because He Cheated, Says Source

Jennifer Lopez and her on-again, off-again boyfriend Beau “Casper” Smart broke up after she caught him cheating, says a source

“She kicked him out because he cheated on her and he got caught,” says the source. “It happened two years ago, and he promised he would never do it again and once he did, she was done.”

Recently, the source says “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.’ ”

While there were reports back in August that they broke up after Smart, 29, failed to attend a party in the Hamptons with Lopez, 47, the source says that is not the case.

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

“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. 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,” says the source. “No one has time for that, especially J. Lo.”

A rep for Smart confirmed that the dancer served as a creative director for a new music video for Wisin that was shot in Mexico this past week but added that everything was “strictly work, nothing personal.”

When news broke of the split in August, a source claimed it was an amicable separation.

“It wasn’t anything dramatic and they were on good terms – it just came to a natural end,” the source told PEOPLE. “They will remain friends and they see each other, but they are not together. It was very amiable.”

Rumors of their romance started back in 2011, but they didn’t speak openly about their relationship until July 2012.
