Roc Nation artist Rita Ora is reportedly dating reality TV star Rob Kardashian. The two were outed as a couple yesterday when a paparrazi caught them having a huge, blowout argument on a street in Hollywood, California. Once Rob realized the argument was being recorded, he ran after the photographer and cornered him in a local spoke shop. The pap yelled out, “He’s attacking me … he chased me … he tried to kill me.” The police came in shortly after Rob could even get to the guy and arrested him. Below is a photo of the two arguing and Rob getting arrested. The cops released Rob Kardashian from custody shortly after his arrest. Rumor has it that Rita and Rob have been dating for a year and were introduced to each other by Romeo Miller. They were also spotted out and about in Rita’s home base of London late last month.
