LONDON: Rihanna is set to blast ex-boyfriend Chris Brown in her new songs.
The 'Umbrella' singer is yet to speak about her volatile relationship with the 20-year-old singer - who recently pleaded guilty to assaulting her and was sentenced to five years probation and six months community labour - for the first time in a track on her upcoming album.
Ne-Yo, who is working with the 21-year-old singer on the record, said: "Expect an edgier, almost angrier Rihanna on this one. Rihanna says some things on this album that you've never heard her say before."
It is thought Rihanna could be planning to sing about the assault, or about the violence which marred the relationship.
Court papers have revealed the pair were involved in at least two other "domestic violence" incidents before the February altercation, during which Chris punched, kicked and choked Rihanna in his car.
Akon is also working with the pop beauty on her new songs, but has no interest in appearing on any of her dark tracks.
He said: "I'm not supposed to say anything but I'm going to work on as many songs as possible with her. I'm going to lighten her up. I don't want an angry Rihanna."
In May, it was claimed Rihanna had been writing a song about killing a cheating partner at the time of the assault.
It was called 'Emergency Room', and was about a women who dreams of exacting revenge by hospitalising her unfaithful partner.
Lyrics include: "I'm going to leave your heart broken on the floor / You're gonna be in the emergency room / I'm standing by your bed / And so tempted to pull out your IV."
It has been claimed the February argument between Chris and Rihanna started after she became angry that he had received a text message from an ex-girlfriend.
