The mask is off on Cameron Diaz.

The 41-year-old actress said one of her proudest moments came when she received the first bound copy of her new self-help book, The Body Book.
She shared this moment with audiences via Twitter on Wednesday in a photo of her holding up the book, pressed close to her heart.
The Charlie's Angels star wore no make-up – only an expression of pride and joy.
Her excitement was captured in the caption: 'One of my proudest moments! Receiving the first bound copy of The Body Book!! @thebodybook LADIES!! I wrote this book for YOU and YOUR BODY.. And I'm so excited to share it with you!! You can pre-order it now. http://amzn.to/1cmXmY6 #loveyouramazingbody'

Cameron considers the book an act of giving back
'She wants to stop their fixation on being thin, and for teenage girls to understand that being healthy is more important,' the source said.
'She wants to use her celebrity to make a difference. She knows she is a role model to girls and she really wants to use that position to do good.
'This book is not about weight, it's about making the right choices.'


Yay or Nay to her nude face?
