Rihanna and Brown have a lengthy history, and most recently the two collaborated on the song Birthday Cake. However, it appears Brown has crossed the line - again.
In the song he tweeted, a remix of Kanye West's Theraflu, he raps "Don't f--k with my old bitches ... like a bad fur ... every industry n--ga done had her.
"Trick or treat like a pumpkin ... just to smash her."
Almost immediately after the song was posted, Rihanna unfollowed Brown - and he did the same to her soon after. Thus, the rumors of the verses being like her have only grown.
