Rihanna thinks Rita Ora has a "lack of respect" for her.
The BBHMM singer is reportedly furious with the 24-year-old singer for recording a song with her ex-boyfriend Chris Brown and objects to the steamy video which is set to accompany the track, Body On Me.
A source told The Sun newspaper: "There's no lost love between them, but this is another example of what Rihanna perceives to be a lack of respect by Rita.
"Chris and Rihanna have a long history and she hit the roof when she heard about Body On Me - especially the video."
The Poison singer has been trailing the clip - which is set to premiere on August 21 - since unveiling the song earlier this week, teasing it is her most "intimate" video yet.
