(Cover) - EN Showbiz - Jennifer Lopez reportedly believes that she and her beau Casper Smart have no "long-term future together."

The 42-year-old superstar and her backup dancer lover Casper began dating shortly after the breakdown of her marriage to Marc Anthony last year.

At the moment Jennifer is performing concerts internationally and Casper choreographs and dances in her show routines.

Hardworking Jennifer, who is also mother to four-year-old twins Max and Emme, is not impressed with Casper's recent behaviour.

"Jen is currently on tour with Enrique Iglesias, and Casper is the head choreographer of her show in which he also dances," a source told Radar Online. "It's tough being on the road -- this isn't Jen's first tour and she has been feeling more like Casper's babysitter than girlfriend. Casper likes to hang out and party with the other dancers and that just isn't Jen's scene. She is all business and is the utmost professional. Jen is absolutely going to break up with him, they just don't have a long-term future together." (C) Cover Media
