Of course, all the Bailey children - Paloma (named as a homage to Picasso), Fenton, 15, and Sascha - have grown up in front of the camera. Catherine unfolds her long limbs (she is like a particularly well-bred foal) and gallops over to the overstuffed bookshelves to grab a wellthumbed copy of The Lady is a Tramp, Bailey's book of portraits of her - as a model, wife, mother, muse. In most of them she is either heavily made up, Eighties-style (all panda eyes) or naked, legs akimbo.
