    Rob Kardashian Claims Rita Ora Cheated on Him With ’20 Dudes’

    Rita and Rob. (WeirPhotos/Splash News)In the words of Rita Ora, "R.I.P" to her relationship with Rob Kardashian. But the reality star is not letting the split go peacefully. On Monday morning, Kardashian lit up his Twitter page with the outrageous claim that the British singer, who he began dating in the spring, had cheated on him with "nearly 20 dudes while we were together," he wrote. "I wonder how many she will sleep with now that we apart … How can a woman who is so busy trying to start her own career have time to be with so many dudes all while in a relationship … I am actually disgusted a woman could give up her body to more than 20 dudes in less than a year's time while trying to start a career."

    The 25-year-old was making such a whiny spectacle that even his sister Khloe chimed in to warn him, "Rob be nice kiddddd," although she also previously added to the dog pile by tweeting, "Cheaters never prosper @RobKardashian ill be home today... Try and smile little brother" — which she later deleted. Rob, who has a "dress sock" line, also came to his senses because he deleted all the offending tweets from his timeline.

    But even though Kardashian took all of his ugly words back, the damage was done. Not long after his Twitter tirade, #RitaWhora was trending on the social network, but it was not only a dig at the singer. "Someone needs to remind him how his sister Kim got famous," tweeted @ItsRM_, which was re-tweeted nearly 1500 times by other users. Added @SmileyBielibz: "Rita Whora? lol Rob Kardashian, I think you got Rita mixed up with your sisters."

    Ora, who celebrated her 22nd birthday in London last week without her boyfriend, has yet to respond to Kardashian's claims. Instead, her Twitter page on Monday was filled with excitement about the announcement of her upcoming tour.
