Rita Ora has claimed that some of her past romances have ended, because she scared guys off with her strong mindedness.

The self-assured Black Widow singer, who has dated Calvin Harris and Rob Kardashian in the past, reckoned her bold confidence made her seem intimidating to some of her ex-boyfriends.

“People tend to feel intimidated by a woman who’s comfortable in her own skin. Some of my relationships have ended because they’ve been intimidated by me. But if you can’t love me, leave me!” she told Hunger TV.

Rita, who is joining the X Factor judging panel alongside Simon Cowell, Cheryl Fernandez-Versini and Nick Grimshaw, compiled her experiences for her new single, Poison.

“It came from my experience in poisonous relationships. I’m not pointing fingers at anybody – it’s basically about all my exes combined,” she explained.

The 24-year-old singer continued: “I just thought that I’ve put enough songs out that are party tunes – that I’m so happy that people like, of course – but I wanted to put something out that was like, ‘You know what, this is what’s getting on my nerves right now’.”

Rita’s second album, the follow-up to her 2012 debut Ora, is expected to be released later this year.
