Jenny's back on the block! Holla!

Jennifer Lopez and boyfriend Casper Smart have called it quits on their relationship, People reports.

"Jennifer and Casper have split. They have not been together for a few weeks," a source dished to 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," the source added.

The pair first began dating back in 2011 after J.Lo's split from husband Marc Anthony, but they've taken several breaks during their romance. The backup dancer recently helped his superstar lady love celebrate her birthday in Las Vegas, and he was in the audience for her Caesar's Palace show on August 13, so something must have happened to cause the sudden split.
