Rita Ora
After Rita Ora split from Rob Kardashian, things got ugly–and fast. Following their split, Kardashian unleashed an ugly social media rant, calling Ora a “whore” and a “cheater.” The “Anywhere” singer responded with a not-so-subtle burn in which she claimed that everyone should have to “sit an exam” before going on Twitter to test their mental stability. To add insult to injury, Ora then claimed that she was never actually IN a real relationship with Kardashian.
