The pictures follow months of them denying dating rumors – with her saying: “He’s a great friend. But the only relationship I’m having now is with the tour bus.”

But the rumors continued, with the pair repeatedly pictured together.

Just last week Robert Kardashian was seen in the crowd as the British singer began the U.S. leg of her tour.

Rita Ora was then pictured in the reality star’s hugely expensive car – with Rob Kardashian tweeting: “This crazy b***h just stole my car.”

Kim Kardashian’s new relationship with rapper Kanye West has helped her find even more fame, and has dominated the gossip pages.
