Diane Keaton is putting pen to paper once again to share her views and tips on beauty, ageing and life as a woman.

I think most women are a little disappointed when they look in the mirror

The Annie Hall star wrote her first memoir, Then Again, last year (11) and now she's expanding her credentials as an author with a lifestyle book.

She says, "We're all obsessed with beauty, no matter who you are. I think most women are a little disappointed when they look in the mirror. I know I am. This book is my way of asking why".

The as-yet-untitled self-help book will be released next year (13).
