Cameron Diaz is expanding her horizons from just acting and reportedly is writing her first book!

The book will focus on the importance of proper nutrition and staying healthy for young girls. A publishing source told E! News, ”She wants to stop their fixation on being thin, and for teenage girls to understand that being healthy is more important. 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.”

Love that!

Along with writing the book, Cameron plans to visit schools across the U.S. to speak to teenagers about healthy eating and their food choices.

As of of now, the book has no title and no deal has officially been made, but she has signed with a literary agent.

We can’t wait to get our hands on a copy when it comes out!

What can we say? 3 is a lucky number for Drew Barrymore!

3 Charlie’s Angels and 3 trips down the isle. Her 5-month engagement to Will Kopelman ended on Saturday, June 2nd, when the lovebirds took the trip down the isle.

Their wedding was a small intimate affair that took place in Barrymore‘s Montecito home. Among some of the guests were Cameron Diaz and Jimmy Fallon. Kopelman’s father was former CEO of Chanel which means Barrymore wore a custom made Lagerfeld design.

Lagerfeld needed to add a few more inches of organza due to Barrymore‘s baby bump!

Drew has yet to confirm her pregnancy but she was seen strutting her little bump on red carpets over the past months.
