Earlier today Rob Kardashian went on a Twitter rant over his break up with Hook-Up #2 star Rita Ora.

The couple went public at the end of October and now Rob has apparently found out she had been cheating on him. Being the mature young man that he is… he took to Twitter to let it all out calling her disgusting for cheating on him with 20 guys this year.

No word yet on if it’s true or not but I don’t think Rita is that type of girl.

The Twitter rant has since been deleted but someone always gets a screenshot… check it out here.
