The Price Tag singer has previously claimed she would get rid of her locks to raise money for charity, but has now confirmed it will be happening sooner than expected.

Speaking to We Love Pop magazine she said: ''I'm going to announce the charity I'm doing it for soon. It's taken a little while to get the ball rolling. It's not as easy as, 'Oh, 'I'm going to shave my head!'

''I want to make it worth it and make sure I raise a lot of money. I can't wait, to be honest. I think I'm going to love it. My hair grows so quick, but it's naturally dark blonde. Seeing my natural roots will be interesting.''

Last year, Jessie said she wanted to shave her head for as many as five charities and she was hoping to raise around £1 million.

She said: ''I'm so ready for it. Bic it, powder it, who cares? My hair will grow back. There are times when I wish I could have done marathons, but with my heart problem I couldn't - but there are things I can do to raise money.

''There are a lot of celebrities who would say, 'I'd shave my hair,' but they wouldn't.''
