After months of rumors about their reported on-again romance, and two highly controversial studio collaborations, it looks like Rihanna is finally breaking off contact with her abusive ex-boyfriend Chris Brown -- at least when it comes to social media. Ri has un-followed Brown on the social networking site, AOL Music reports.

Rihanna tweeted birthday wishes to Brown on his birthday last weekend (May 5), but perhaps she was getting fed up with seeing endless PDA-packed photos of her ex with his new main squeeze, aspiring model Karrueche Tran. Who wouldn't? But according to TMZ, Rihanna axed her former flame from the list of Tweeters she follows just hours after Breezy released a freestyle rap that may have taken a major jab at her.

The R&B singer and sometimes rapper released a verse he recorded over Kanye West's new track, "Way Too Cold," formerly "Theraflu." "Don't f--k with my old bitch it's like a bad fur /Every industry n---a done had her /Shook the tree like a pumpkin just to smash her /Bitch is breaking codes, but I'm the password," he rhymes.

Does that sound like a RiRi diss to you? If so, was it the straw that broke the camel's back? Listen to the track below and let us know what you think on Twitter, @aolmusic.
