Rob Kardashian has refuted claims he ever called Rita Ora a "whore".

The reality TV star took to Twitter yesterday to slam his former lover for "cheating" on him - with many understanding that the woman in question was Ora.

Kardashian has denied reports he ever labelled the singer a "whore" and blames the public for blowing the tweets out of proportion.

He wrote on his Twitter page: "Just so we clear I never once mentioned "Rita Ora" in any of my tweets or even used the word "whore" and I never would. I Respect Women. Sad that the media created negativity for a young artist new to the game that is working so hard to make it. Never mentioned any names.

He added: "I speak truth. I'm a very Real dude and everything I say I mean... But never called anyone specific a whore and said any names. You all did (sic)"

The pair had been dating for a while, but recent reports suggested that the couple had split. Kardashian confirmed the rumours after blaming her for ruining their romance with her dishonest and "disgusting" behaviour.

He wrote: "She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we're apart. But I mean 20?!!!"

"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'm actually disgusted a woman could give up her body to more than 20 in less than a year's time while trying to start a career (sic)."

Kardashian deleted the tweets shortly after posting them.

Meanwhile, in an interview with Glamour magazine, Ora said that the relationship didn't work out because of their conflicting schedules.

She explained: "I'm not going out with Rob. We were close for a while, but it didn't work because I was never there. I was like a ghost. I used to get so frustrated with myself and then wonder why I was angry, so I decided it was best to keep it friendly - especially at the moment, when there's so much going on."
