London, December 4 (ANI): Rob Kardashian has seemingly launched an astonishing attack on Rita Ora following their break-up, accusing her of cheating on him with "20 dudes".
The pair had been rumoured to be an item during a secretive year-long romance.
But now Kim's brother claims his ex had a series of flings - and took to Twitter to vent his rage.
In a string of angry tweets, Rob wrote: "I'm 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.
"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?
"She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we apart. But I mean 20?!
Sources blamed their break-up on the difficulties of their long-distance relationship and busy work schedules.
Rob, who later deleted his scathing accusations, received support from his sister Khloe over his outburst.
She wrote: "Cheaters never prosper @RobKardashian ill be home today... Try and smile little brother." (ANI)
