Jessie J can't decide what to wear to the Brit Awards tonight, so is threatening to go naked.

The singer has been nominated for three prizes at the prestigious UK music event this year. She is in the running for Best Female, Best Breakthrough & Best single for Price Tag.

Jessie is looking forward to the ceremony, but has no idea which eye-catching outfit to choose. The star is famed for her outrageously glamorous catsuits, but admits she is running out of time and may even shock the audience with a casual look.

"I would say I've got an outfit planned but I'd be lying. So at the moment I'm going naked," she told British newspaper The Sun. "I wore a see-through catsuit at The Brits launch last month and everyone was like, 'She wore the same thing a year before.'

"Maybe I should go casual in Nike Jordans, jeans, woolly hat, T-shirt. No make-up."

Jessie J has enjoyed worldwide success in the past year after winning the Critics' Choice prize. The award is given to new British acts that are tipped for future success and previous recipients include Adele, Ellie Goulding and Florence + the Machine.

Jessie, 23, is grateful to the Brit Awards for kick-starting her career.

"I just feel so, so honoured to be associated with British music. Last year I won the Critics' Choice award. But I didn't know what the year would bring or if people would buy my album, whether they would like me or not like me. Or hate me. So a year on to be nominated for three awards is amazing," she smiled.

"Tinie Tempah is fun to hang out with and I can't wait to see Adele perform and give her a hug and tell her how proud I am of her. Ed Sheeran is great to watch too. I think he'll definitely collect an award."

The Brit Awards will take place on Tuesday evening at the O2 Arena in London.
