Rihanna is vowing not to have any more contact with old-flame Chris Brown following his explosive, June 4 screaming match with Karrueche Tran.

A source tells Hollywood Life the "Diamonds" singer is completely over the "troubled" Brown after police had to be called to Tran's home when he appeared uninvited and began beating on her door nonstop.

"Rihanna feels really bad that he is obviously very troubled and in pain but she is not going to reach out to him and help," a source added. "He has had plenty of chances and she just doesn't want to get into it. That was her former life and she got out of it and she likes the world she is living in now - way less drama!"

Reports are the 26-year-old Brown first forced his way into Tran's car and refused to leave. After a "massive screaming match," between the two Brown later showed up at his ex's apartment, where police had to be called by neighbors to calm all the noise.

Brown and Rihanna first infamously split in early February 2009 after he physically attacked her, leading to him ultimately being convicted of assault and sentenced to serve five-year's probation and perform 1,400 hours of "labor oriented service."

And it's not as if Rihanna doesn't have plenty of other things to keep her busy. Besides being rumored to be dating international soccer star Karim Benzema, the sultry diva has a new album coming out that's soon slated to hit stores.

TMZ reports she and Benzema were recently spotted in New York City on a 5 a.m. breakfast date at the popular Cuban diner Coppelia. The 27-year-old Benzema stars on the French national team, and the two were described as looking cozy inside the eatery.
