You can't expect your love life to stay private if you're dating a Kardashian.

Rob Kardashian has apparently split up with his girlfriend, Roc Nation singer Rita Ora, and he hopped on Twitter to put her on blast. According to Rob's tweets, Rita was sleeping with numerous other men while they were together.

"She cheated on me with 20 dudes while we were together, I wonder how many she will sleep with now that we apart. I mean 20?!" he tweeted. "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?!?!",/p>

"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," Rob continued.

Big sis Khloe also seemed to endorse the Rita-was-a-cheata story.

"Cheaters never prosper," she tweeted. "@RobKardashian I’ll be home today … Try and smile little brother."

"I love you," he replied.

Wow.
