Elettra Wiedemann is the new face of Coast.

The 28-year-old beauty - who is the daughter of Isabella Rossellini and grandaughter of Ingrid Bergman - was chosen to showcase the brand's new collection of occasionwear because of her ''timeless'' beauty.

Five bespoke Stella McCartney bags will go up for auction for charity today (29.03.12).
