Rihanna is furious that Chris Brown is putting a duet with her on his upcoming album.
The 'Fine China' hitmaker was originally planning to axe the track, 'Put It Up', from his new album, 'X' after he and the 'Stay' singer ended their on/off relationship for good earlier this year, but announced on Twitter this week that his ex-girlfriend, 25, will definitely be making an appearance on the record.
The 24-year-old star, who is still on probation for beating Rihanna in 2009, wrote on Thursday (04.07.13): ''New album features @NICKIMINAJ, Kendrick, @rihanna, @KELLYROWLAND, @wizkhalifa, @bobatl and more surprises to come. 'X'''
Rihanna appeared to be less than impressed by his decision to release their track, recorded when they were still together, tweeting shortly after his announcement: ''Phuck O.utta H.ere B.***h.''
She also posted a photo on Instagram featuring the words: ''B***h you will die, be born again, die and be born again before I ever do a song with you b***h.''
Sources close to Chris, who is rumoured to have reunited with his model ex-girlfriend Karrueche Tran, previously said he wasn't planning to let anyone hear the track.
One insider recently said: ''Record execs wanted that song on there, but Chris said he would rather not and wouldn't allow the record to be released unless they took it off.
''They're still hoping to convince Chris or pay him more to change his mind because it would be a hit. The record hasn't been pressed yet, so things can change, but at this point he's not changing his mind.''
Prior to their break up, he said working with Rihanna was ''effortless''.
He explained: ''It flows easily. What works with us is we have similar ways of creating music.''
