Ah, there’s nothing less dignified than a Twitter spat with an ex. The latest couple to forget just how many thousands of people are watching, is Rita Ora and Rob Kardashian. The pair, who always remained pretty coy about their relationship until a few months ago, recently split and it looks as though Rob is pretty mad to learn that Rita hadn’t exactly been faithful to him in their time together. It’s a brave girl that messes with the Kardashian publicity machine but so far it looks as though Rita has the upper hand on this one, despite what she’s been accused of.

Both Rita and Rob have deleted their offending Twitter messages but they weren’t so quick to delete them that no one saw them and New York Daily News have reproduced the insulting exchange for all to see. Rob Kardashian may not have mentioned Rita by name, but she responded as if he was addressing her, so we’re guessing her conscience was pricked by what he was saying. ““She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we apart? (sic) But I mean 20?!!!” came the tweet from Rob. And Rita’s response? “Rob’s d--k was wack, I had to go get it somewhere else,” to which he replied “So you let me get you pregnant and you let others hit raw?”

Cue a slew of supportive messages from the Kardashian clan, making Rita out to be a big bad monster. And cue a Glamour magazine cover shoot, complete with an interview from Rita explaining that it was simply her busy schedule that drove them apart. Not the 20 guys she allegedly slept with. The busy schedule. Got that?
