READ: Rosie Huntington-Whiteley lingerie for Marks & Spencer: the new instalment Valletta, who started modelling aged 15, has appeared in campaigns for the likes of Versace, Louis Vuitton and Gucci and on the cover of publications such as Vogue , Harper's Bazaar and W . In recent years she has made the move into acting, appearing in Hitch and Raising Helen but still scores big fashion jobs, such as the autumn/winter 2012 Pucci campaign. "It's a real honour to work with such an iconic British brand like M&S. I've loved modelling the per una collection, it's great to see the quality and attention to detail that has gone into each piece, yet it's still so reasonable," said Valletta. The idea of affordable luxury is something that's unique to the British high street and something that M&S does very well. The campaign was shot by Swedish photographer Andreas Sjodin and shows off per una's autumn/winter 2012 range. "Amber embodies the classic femininity the per una brand has become renowned and loved for whilst also being the perfect ambassador to introduce the sleek and sophisticated fresh direction for per una this season," said Steve Sharp, executive director for marketing at M&S.
