Rob Kardashian vs. Rita Ora (2012)
Back in 2012 Rob called out his ex Rita Ora for cheating on him during their relationship (I know, then he cheated on Adrienne two years later...don't worry. We'll get to that). Rita Ora apparently replied "Rob's dick was wack, I had to get it from somewhere else." #yikes. All tweets have since been removed from both star's Twitters, but the internet is forever. Winner: Rob. As Khloé said, cheaters never prosper.
