Rob Kardashian can get really nasty when he’s upset, that much was clear on this week’s episode of Kourtney and Kim Take Miami.

The heartbroken Kardashian brother, who had just broken up with his girlfriend Rita Ora, decided to take it out on his sister Kim after she told him to stop posting negative tweets about his ex-girl.

This prompted Rob to say some very mean things to his sister. 

“She’s the one that’s in the wrong,” Kourtney said of Ora, “but she’ll probably try to make it like you’re in the wrong.”

Kim was more blunt, telling him, “Don’t post anything else — everyone has problems,” but Rob defiantly insisted he had to respond, lest people think he’s a “b*tch.”

Things got out of control when Rob sent Kim a text message. 

Kim revealed he texted her saying, “I hope your sex tape haunts you for the rest of your life, and I’m going to publicly bash you and Kanye.”

Ouch! Even the biggest Kim K. hater can admit that is a low blow.

Rob later apologized for his harsh words, telling Kim, “I appreciate you being mature and calling me instead of dragging this fight out.”

Let’s hope Rob can get these mood swings under control!
