Rihanna unfollow Chris Brown on twitter

Rihanna made a big step towards removing Chris Brown

The song is a remix to Kanye West's "TheraFlu" with Brown freestylin' the verse, "Don't f*ck with my

old b***hes ... like a bad fur ... every industry n*gga done had her," adding, "Trick or treat like a pumpkin ... just to smash her."

Hours after the tune dropped, RiRi stopped following her ex-boyfriend on Twitter, leaving many to assume that Rihanna thought the diss was aimed directly at her.

Not long after the "You Da One" singer cut the Twitter ties, Brown followed suit by un-following his ex, but not before tweeting a message about Rihanna's reaction to the rap.

Last night, Brown messaged, "Assumptions! I didn't say any names so if u took offense to it then its something you feel guilty about."

Earlier today, the Barbadian beauty took a shot back at Brown by tweeting," .....That's cuz her name iz Rihanna".
