Christy Turlington is the new face of Yves Saint Laurent

The 40-year-old supermodel will front the fashion house's upcoming Autumn/Winter campaign, taking over from German beauty Claudia Schiffer, who starred in their most recent series of advertisements.

Christy - who has two children, Grace, five, and three-year-old Finn with husband Edward Burns -fronted YSL's campaign five years ago.

Her latest pictures, which were taken by photographers Inez van Lamsweerde and Vinoodh Matadin, will appear in fashion magazines from later this month.
