6. Rita Ora
Poison singer Rita Ora supposedly slept with “20 dudes” in a bid to kick start her career, according to her one-time boyfriend, Rob Kardashian.
When the pair broke up in 2012, Rob went on a crazed Twitter rant all about how he had been cheated on just so his girlfriend could boost her own career.
He tweeted: “She cheated on me with nearly 20 dudes while we were together. I wonder how many she will sleep with now we’re apart?”
Then in a separate tweet: “I’m actually disgusted a woman could give up her body to more than 20 dudes in less than a year’s time trying to start a career”.
It was his older sister, Khloe Kardashian, who managed to calm him down when she tweeted: “Rob, be nice kid”. The undignified messages were soon taken down and replaced with a less scandalous rant where he preached “loyalty” and “self-respect”.
Ora since went on to have a relationship with Calvin Harris for a year and has now landed a judge’s seat on the UK’s X Factor.
