Jessie J is blonde, buzzed and beautiful! Less than two weeks after the pop star shaved her brunette bob for England's 25th Annual Comic Relief fundraiser, the British singer showed off her lighter locks on Instagram March 26.
"It's my birthday and I'll be blonde if I want to," the 25-year-old singer wrote in the photo caption. "Thank you in advance for all the birthday tweets and messages," she tweeted March 26. "I feel so happy right now!"
The musician -- known for hit singles like "Price Tag" and "Domino" -- first told Us Weekly about her plans to shave her head for charity in April 2012. "I can't wait," she revealed. "I want to raise money for cancer, and also, hair isn't that important at the end of the day, so I don't mind!"
