Jessie J Tickets

Jessie J has decided to shave her head to raise money for charity.

The 'Do It Like A Dude' singer, who is known for her signature blunt bob and black locks, will be making the dramatic cut next year.

In a series of tweets, the 23-year-old says that it's "just hair" and will grow back but she's hoping to help people who are less fortunate than herself.

Jessie J, who has been recovering from a broken foot, tweeted the news to her fans: "I have decided I will be shaving my head next year to raise money for charity. To me its just hair, to those suffering its a chance to live.

"I am feeling so reflective & emotional. I just want to say to every fan of mine who has thanked me for helping them - I am so proud of all of you. Music is not just to dance to its to also heal."

She continued: "Its hair, It will grow back. Even if it takes two years, if it saves lives its worth it. Even if its one life that's something."
