The Keeping Up With The Kardashians star took to Twitter, this morning, and blasted an unnamed person who from the looks of it is Rita Ora.
"She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we apart," he posted.
"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," added Kardashian.
Khloe Kardashian also got in on the game and tweeted: "Cheaters never prosper @RobKardashian ill be home today... Try and smile little brother."
She added: “"Rob be nice kiddddd.”
All of the above mentioned comments have since been deleted from Twitter, reports Toofab.com.
