Rihanna and Chris Brown's rocky relationship has suffered yet another blow, and their feud has become so heated that the pair recently stopped following each other on Twitter.
While there has reportedly been tension between the singers for several weeks due to Brown's relationship with model Karrueche Tran, it is said to be his lyrics in his remixed version of Kanye West's "Way Too Cold" (Theraflu) which prompted Rihanna to snap, according to TMZ.
"Don't f--- with my old b---- it's like a bad fur / Every industry n---- done had her / Shook the tree like a pumpkin just to smash her / B---- is breaking codes, but I'm the password," Brown said in his freestyle rap.
After what may have been a confrontation with Rihanna, 24, a heated Brown immediately took to Twitter and appeared to direct his tweet at Rihanna, who he stopped following shortly after she stopped following him on Thursday.
"Assumptions! I didn't say any names so if u took offense to it then its something you feel guilty about," Brown tweeted.
Fans suspect that the "Where Have You Been" singer felt disrespected by the lyrics, particularly after she risked her career in order to collaborate on a recent song with Brown, 23.

The former couple teamed up for "Birthday Cake" three years after Brown physically abused Rihanna, ending their relationship. Doing so reportedly angered Rihanna's longtime mentor Jay-Z.
"Jay was absolutely disgusted by what Chris did to Rihanna. Jay doesn't understand how a man could ever lay hands on a woman; it just goes against who he is and about. Chris is absolutely dead to Jay, he wants nothing to do with him ever," a source told Radar Online.
Reports of a reconciliation surfaced after their song was released, although Brown was quick to shut down the rumors after validating his relationship with Tran.
Rihanna and Tran have since been involved in an alleged Twitter war, taking digs at one another through nasty tweets which some attribute to the "We Found Love" singer's jealousy and desire to rekindle her relationship with Brown.
Rihanna and Brown have yet to address rumors of their ongoing feud.
