Up until now, it’s remained unclear whether accusations that Rita Ora actually cheated on Rob Kardashian were true.

But Us Weekly reports that Rita did cheat on Rob — with Moneyball actor Jonah Hill.

A source told the mag that the British singer met Jonah at a club in New York and ended up going home with him. When Rob found out, he ended the relationship.

All of this may explain the Kardashian’s angry Twitter rant following his breakup with Rita.

While cheating with one guy is not the same as 20, it’s still not a great way to end a relationship!
