PICS: Rob Kardashian Slams Rita Ora's Alleged Infidelity On Twitter

Somebody should have told British singer-songwriter Rita Ora, 22, not to mess with the Kardashians. The "Hot Right Now" and "R.I.P." singer, is getting the brunt of ex Rob Kardashian's Twitter rage since the two recently split. Kardashian, 25, is claiming that Ora was repeatedly unfaithful during their brief jaunt together that reportedly started late this summer.

"She cheated on me with nearly 20 dudes while we were together," Kardashian tweeted. "I wonder how many she will sleep with now that we are apart? But I mean 20?!!!" Though the tweet was later taken down, reports Examiner, along with a supportive one from big sis Khloe Kardashian, 28, that read, "Cheaters never prosper @RobKardashian ill be home today… Try and smile little brother," a few other post-breakup tweets surfaced later on Rob's Twitter account.

"When a woman cheats on you with one man I can live with that," Kardashian continued on Monday. "People make mistakes, trust me. I have forgiven numerous times … But when a woman disrespects herself by messing with more than 20 men all while being in a relationship with a Faithful man…".

And later, "I just don't get how a woman can do that to her body. And your career hasn't even launched yet. I don't put up with sloppiness. LOYALTY."

But the Kardashians weren't the only ones who were fighting mad about the alleged infidelity on Ora's part. It didn't take long for "Rita Whora" to start trending on Twitter.
