The `Nobody`s Perfect` hitmaker has revealed both she and her family have been targeted by hate-filled individuals since she achieved pop success, but she refuses to waste her time worrying about what might happen to her.

In an interview in Q magazine, she said: "I`ve had people say, `I wanna kill you and your family.` Death threats. I`ve had people say, `I hope you get HIV and throat cancer at the same time.?

"I think the world has become obsessed with hating things. But people who wanna spread bad energy, I ain`t got time for them to be in my psyche."

The 23-year-old star - who is openly bisexual and abstains from drinking alcohol because of health problems she has suffered, including having a minor stroke aged 18 - has also revealed there have been rumours she is a devil worshipper because she makes an OK sign with her hands in her video for single `Price Tag`.

She said: "This is 666 apparently. And to me it`s saying OK. People have played `Do It Like a Dude` backwards and said they can hear the devil."
