Don’t mess with a Kardashian! Like as in, ever. Because they have a huge Twitter following and can mess you back pretty badly.

Rob Kardashian who reportedly broke up with Rita Ora last week Tweeted an irate message about an unnamed cheating ex-girlfriend yesterday. The message read:

“She cheated on me with nearly 20 dudes while we were together.  I wonder how many she will sleep with now that we apart? But I mean 20?!!!

Rob did not name the ex-girlfriend but that did not stop “Rita Whora” from trending for a minute right after Rob’s Twitter outburst–which was quickly deleted by the reality star by the way.

Rob’s older sister Khloé Kardashian Odom dished out some public advice to her baby bro by also taking to Twitter: “Rob be nice kiddddd….Social media is so much drama. Hehehe thank goodness there was no social media when I was younger. Too much drama in the LBC.”

Rob felt like explaining himself. “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…”
