Rihanna found out via social networking website Twitter that BBC Radio 1 had changed the name of her racy tune S&M, to Come On.
Several words from the song, including 'chains' and 'sex' had been cut.
The Barbadian beauty didn't seem impressed, posting on her Twitter, 'Are you f****** kidding me?'
Although it was actually Def Jam, her own record label, that made the changes to the song so it still got played.
The video for the 22-year-old's new single has already been banned in several countries.
