Rihanna deletes Chris Brown from her Twitter account as ex 'disses her in new track'

They recently collaborated on a new song and were rumoured to be reigniting their former romance. But it appears Rihanna and her ex-boyfriend Chris Brown have fallen out again after the singer released a remixed track last night in which he apparently dissed the Barbadian star.
Rihanna, 24, reacted by 'unfollowing' Chris on her Twitter account - and he quickly followed suit, deleting her as well.

Brown,23, released a version of Kanye West' TheraFlu last night in which he raps: 'Don't f*** with my old b*****s ... like a bad fur ... every industry n***** done had her,' continuing: 'Trick or treat like a pumpkin ... just to smash her.'

Taking offence? Rihanna pictured on Monday at the Met Gala in New York

After speculation about the track started doing the rounds on the internet, Brown tweeted where he apparently addressed Rihanna. Posting a picture of himself on Twitter, he also wrote: 'Assumptions! I didn't say any names so if u took offense [sic] to it then its something you feel guilty about.'

His telling remark would seem to suggest some beef between the pair, who recently appeared to be on better terms, three years after Brown viciously assaulted his then-girlfriend
