It's all about the money, money, money!
The "Price Tag" singer took to her Twitter account to confirm and announce the details of her much talked about charity head shave.
She tweeted: "A year ago I said "I'm gonna shave my head for charity"..."
"I have spent a long time making sure that when I do shave my head I raise as much money as possible for charity..."
"I have been waiting for the perfect time and the right charity.. But also a charity that can get my amazing fans involved too.."
"I am SO excited and honoured to be able to finally officially announce I will be shaving my head LIVE for you ALL to watch in March 2013 for @rednoseday :D #letsraisesomemoney"
