Jennifer Lopez and Casper Smart have split after two and a half years together, according to multiple reports.

"It has actually been an amicable process that started a few months ago," an insider tells Us Weekly. "It wasn't an easy decision, but they decided to stay friends ... Their relationship couldn't work with the distance. He started trying to establish his own life and career, and she is so focused on hers, and they just couldn't be all about each other anymore."

After several websites claimed that Casper was fooling around with transsexual models, we figured it would only be a matter of time. Last week it was reported that Casper hooked up with trans model Sofie Vissa, and a few days later The Dirty found a second girl, Xristina Marie. The site added, "According to our source the couple met in Miami and Casper Smart was 100% aware that Xristina is a transsexual."

Still, a source close to the couple told Us Weekly that the story was "100 percent not true," adding, "The scandal had nothing to do with it. He insists none of that is true and she believes him." The source adds that Lopez is "doing fine" and she's "focused on promoting the album. They are both in a good place now."

Lopez, 44, and Smart, 27, started dating in November 2011, just four months after she split from Marc Anthony, with whom she has twins Max and Emme, 6. Lopez was previously wed to Cris Judd and Ojani Noa, and from 2002-2003 she was engaged to Ben Affleck.

Wonder who J. Lo will step out with next?
