Supermodel Kate Moss has signed up to appear in the TV adaptation of comedian David Walliams' bestselling children's book "The Boy In The Dress".
 
 It will debut over Christmas this year, reports contactmusic.com.
 
 Actresses Jennnifer Saunders and Meera Syal will also star alongside 12-year-old newcomer Billy Kennedy.
 
 Walliams said: "We have put together a dream cast for this, the first of my children's books and for many, still my best. It is a funny and poignant story about what it is to be different. I hope it will make everyone who sees it, young and old, stop and think."
 
 Reports suggest Moss will play herself in a dream scene.
