Rita Ora has reportedly "upset" Cara Delevingne by falling out with Azealia Banks.

The singer made headlines last week when she engaged in a public spat with the hip-hop star through the social networking website.

The cause for their conflict is rumoured to be model-of-the-moment Cara, who is a close friend of both stars.

The bisexual 212 rapper is reportedly jealous of comments Rita made in an interview where she branded Cara her "wifey".

It has now been claimed that Cara is not happy about her two female friends' spat and is desperate for them to heal their rift.

"[Cara] has been texting them both 24/7 trying to help them sort things," a friend revealed to the British edition of Grazia magazine. "She's trying not to take sides. It's really upset her how they have fallen out."

The 20-year-old British catwalk queen, who has revealed she "plays for more than one team", has long enjoyed a flirtatious Twitter relationship with both singers.

The in-demand beauty attended the Mermaid Ball in New York last October as Azealia's date, which seems to have meant more to the singer than first thought.

"Azealia and Cara were close until Rita came on the scene. Rita actually told people she’d wanted to work with the rapper," a source previously explained.

"But when she started calling Cara ‘wifey’, Azealia got possessive and has held a grudge ever since.”
