5. Rita Ora
Once Rihanna’s tabloid best friend, the British singer is regularly in the spotlight for her promiscuous love life. Her list of conquests includes some of Hollywood’s biggest names, like Bruno Mars, Supermodel Cara Delevingne, Rob Kardashian, Calvin Harris, Dave Gardner and Ricky Hil. After concluding her relationship with Rob Kardashian, he claimed that she had slept with 20 different men in the course of a year. Quite the cougar you are, Miss Ora!
