It’s over between singer Monica and rapper Rocko. Rumors suggest that Rocko (real name: Rodney Hill Jr.) cheated on Mo and the other woman has been harassing Monica ever since she got her phone number.

According to the girl, she and Rocko have been getting it in for the past few months. She claims that she’s been going all around Atlanta with dude (restaurants, the studio, etc) and has been carrying on a SEXUAL relationship for months. But it gets even worse, MediaTakeOut.com learned that the JUMPOFF and her girlfriends have gotten Monica’s phone number and have begun harassing her. One of this jumpoff friends reached out to MediaTakeOut.com to explain how they frequently call Monica – often laughing on the phone and taunting her.

All of this drama has prompted Monica to end her engagement/relationship to Rocko, reports Media Take Out.
