Jennifer Lopez, Casper Smart on verge of break up?

Singer Jennifer Lopez and her dancer beau Casper Smart's relationship is reportedly going through a rough patch and the two are on verge of break up.

"Jen is currently on tour with Enrique Iglesias, and Casper is the head choreographer of her show in which he also dances. 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," radaronline.com quoted a source as saying.

"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," the source added.

Lopez and Smart began dating last autumn, just a few months after her seven-year marriage to Marc Anthony ended in July 2011.
