#3 – Rob Kardashian vs. Rita Ora

In another case of tweeting one’s dirty laundry… Rob Kardashian took to twitter after his split with Rita Ora in December 2012.

He tweeted: “She cheated on me with nearly 20 dudes while we were together… But I mean 20?!!!!” and claimed that he had got her pregnant.

Ora broke her silence on the tirade in March stating: “You should have to sit an exam before you go on Twitter to see if you’re mentally stable.”

Ouch.
