It was a classic 2012 Tinseltown romance.

It began on Twitter, when reality star Rob Kardashian posted photos of himself cozying up with singer Rita Ora to his 3 million followers.

Then, a few short months later (in true Kardashian form), the famous sibling took to the social media page yet again to confirm the pair had split. The reason? According to Kardashian, Ora cheated on him with 20 different men.

"She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we apart? But I mean 20?!!!," Kardashian tweeted on Monday, according to The Insider. "How can a woman who is so busy trying to start her own career have time to be with so many dudes all while in a relationship?!"
