It will be all about the money, money, money for Jessie J when she shaves her head live on television to raise money for Comic Relief.
The singer, who will go under the razor on BBC1 on Friday March 15, said: "Shaving my head for charity is something I've promised to do for a long time and Comic Relief has given me the opportunity to try and raise as much money as possible for good causes by doing it.
"I've loved watching Red Nose Day since I was a kid and I'm so excited to join this year's team of celebrity fundraisers and help support the campaign. So this Red Nose Day I'll be shaving my head live on the night of TV.
"I won't deny that I'm nervous but I am also honoured to be part of this year's campaign.
"Together with help from the UK public, we are on a mission to raise more money than ever before for Red Nose Day. So come on, let's do it."
This year's fundraising efforts will also be boosted by pop idols One Direction who have recorded a new version of the Blondie classic One Way Or Another for the Red Nose Day single.
The boyband, who rose to fame on the X Factor, will perform the song for the first time at the Brit Awards next month.
Niall Horan said: "We are really excited to be part of Red Nose Day this year.
"We recorded Blondie's One Way Or Another and we really want the song to raise lots of money and for people to show their support by going out and buying themselves a copy."
Supporters can also raise money by buying special T-Shirts designed by Stella McCartney.
