Jessie J claims she has received death threats from people who are so incensed by her music.
The Brit Award-winning singer - whose hits include Price Tag and Do It Like A Dude - admits she is like "Marmite", by dividing opinion.
And she said that along with numerous insults, she has now been the victim of nasty threats.
"I've had people say 'I wanna kill you and your family'," the raven-haired 23-year-old told Q magazine. "Death threats. I've had people say I hope you get HIV and throat cancer at the same time."
Jessie, who landed the Critics Choice award at the Brits in February, said she had also been insulted about her looks. "They say I look like a drag queen," she said.
And the singer said she had prompted internet rumours that she is a devil worshipper because of an "OK" gesture she made with her hand in the Price Tag video.
"This is 666 apparently," she said of the hand signal. "And to me it's saying 'OK'. People have played Do It Like A Dude backwards and said they can hear the devil.
"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."
Jessie - who is teetotal and avoids caffeine because of health problems she has had since her childhood - said she had turned down lucrative deals with drinks firms for "brands I don't even drink".
"I'm not someone who has ever done anything for money," she told the August issue of Q.
