Actress Cameron Diaz wants common people to be on the cover of the second book that she is penning. It will center around the mental, physical and emotional journey of ageing.

After "The Body Book: The Law of Hunger, the Science of Strength, and Other Ways to Love Your Amazing Body", her first book which landed her in the The New York Times' bestseller list, Diaz is working on "The Longevity Book", reports eonline.com.

"It is centered around the mental, physical and emotional journey of ageing, and as we diligently put the finishing touches on the book, we'd like to ask for your help once more. This book is for you and about you, and that's why we'd like to see you on the cover. Much like the cover of the Body Book, under the jacket, where we featured women of all different shapes, sizes, builds and ethnicities,` she wrote on her website.

Instead of full-length shots, Diaz is asking fans to send a candid selfie for a chance to be one of the 50 women included.

If selected, the lucky winners won't just get the honour of having their face printed on a Cameron's guaranteed bestseller, they will also get a signed copy delivered to their door.

Last date to submit the best selfie is November 20.
