Rob Kardashian took to Twitter on Monday to publicize an accusation that his rumored girlfriend, Rita Ora, cheating on him with 20 different people. 

He wrote the following posts: 

"When a woman cheats on you with one man I can live with that. 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...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.

"This is a lesson to all the young women out there to not have unprotected sex with multiple men especially while in a relationship. RESPECT THY SELF!"

Kardashian and Ora have been reportedly dating for the last several months, according to The Inquisitr, though they never publicly confirmed their relationship. The news report added that after Kardashian's Twitter posts on Monday, the phrase "Rita Whore" started trending on the social media website. 

A source told The Sun about Kardashian and Ora's relationship, "Rob has now deleted everything on Twitter that reminds him of Rita." The publication also said that Kardashian has since unfollowed the singer on Twitter and deleted all photos of Ora on his Instagram. 

Though they posed together in a number of Twitter pictures, Ora recently spoke to Glamour magazine about falling in love and said in specific that she is not dating Kardashian. 

"In 22 years, there's been nothing. I've had young fascinations but never love," she said. "I'm scared of letting my guard down, and if I fell in love with someone now, he'd have to try ten times harder to break it down."

When Kardashian was mentioned by the reporter, Ora said, "He's a great friend. But the only relationship I'm having now is with the tour bus."
