The 'Domino' hitmaker, who has previously claimed she would get rid of her tresses to raise money for charity, said she is excited at the prospect of seeing her natural hair color, reported Contactmusic.
"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," she said.
Jessie, 24, will join the likes of Natalie Portman, Anne Hathaway and Demi Moore, who have all previously shorn off their long locks.
