The Olsen sisters have just released their new book

But we can't figure out who that is on the cover? Have they morphed faces into one? Is it Mary Kate after a pampering session or Ashley doing her best demure pose?

The publication called Influence has been touted as a 'coffee table book' about fashion. Ashley's statement about it reads: "Mary-Kate and I have filled `Influence' with the most interesting, challenging, creative people we know — the ones who helped pave the way for us and our generation," said Ashley Olsen.

Mary Kate added: "Ashley and I interviewed the people who have inspired us, with the hope that they will inspire and teach others".

Predicably some of these ' influential' people include themselves with exclusive pics but some of the world's top photographers and a variety of other never-before-seen materials and interviews from Mary-Kate and Ashley's personal collections. If you want a copy you'll have to wait until October - the price is £16 on Amazon.
