Those Kardashians can play a MEAN game of verbal hardball!
When Rob Kardashian was going through a tough time concerning his sort-of relationship with British singer Rita Ora, dude decided to lash out at his SISTER Kim Kardashian and her baby-dady Kanye West!!
Rob texted Kim:
"I hope your sex tape haunts you for the rest of your life, and I’m going to publicly bash you and Kanye."
HOT SH*T those are some FIERY fighting words!
BUT, Rob soon realized he was being unfair by taking his Rita frustrations out on those closest to him (and let us not forget about his Twitter rants!), and eventually apologized.
Robbie finally expressed:
"Obviously the things I said to you in the text message, I was just being mean."
Good to know Rob came to his senses, and that he didn't make it his life's goal to destroy his sister and her rapper lover…
Cause that would just get AWKWARD at family functions with Rob yelling out stuff about Kim's sex tape! LOLz!
Ch-ch-check out some snaps of Rob and Rita when they were "dating" (below)!
