Is Rita Ora singing 'R.I.P.' to her "romance" with Rob Kardashian? It appears she is, and because she cheated him... a lot. That is, if you believe his deleted tweets.

Word is the two have split, even though Ora went on record to say that it wasn't even a real relationship back in the summer. In her Complex cover story, Jay-Z's protégé said that they were good friends, that they had each other's back and that things were casual. She also said it wasn't "really a relationship," which had to sting for Rob K.

Then they shared photos of fake tattoos of each other's names and they posted romantic photos on Twitter, further confusing the world and making themselves seem like a true "Are they or aren't they?" couple. For those who consider Ora to be copying off Rihanna in her sound and her style, they can accuse her of doing do the same with the handling of her romance. Ora and Kardashian's status was never quite clear, and neither is Chris Brown and Rihanna's, as we speak.

Now, a source has told The Sun that things are kaput for the pair, due to the nature of their long-distance relationship, since Ora is based in the U.K. and Kim's brother resides in Los Angeles.

The insider said, "It’s really sad – they really liked each other but with him living in L.A. and her over in London, it was becoming impossible to maintain a relationship. They’d only decided to go public with the romance a couple of months ago so as not to put any pressure on themselves but they’ve already split. Rob has now deleted everything on Twitter that reminds him of Rita."

Kardashian supposedly went off about Ora on Twitter this morning (Dec. 3), accusing her of cheating on him with at least 20 other guys. Whoa. The tweets have since been deleted, but they were captured here. Kardashian doesn't say Ora by name, but does reference someone trying to jumpstart her career, which seems to point to the singer.
