Famed photographer Mario Testino was the man of the hour as he received the Moet & Chandon Etoile Award in London last night. He was joined by Sienna Miller, Kate Moss, and Rosie Huntington-Whiteley for the evening, which was held at the Park Lane Hotel. Sienna posed with Mario on her way into the event, and Kate covered up her gown with a neutral coat while Rosie showed a little leg on the carpet. All three ladies have worked with Mario in the past, with the photog most recently snapping Rosie for the Burberry Body campaign and capturing Kate's gorgeous wedding photos for Vogue. It's been a busy week in England with the start of London Fashion Week, and Sienna showed up for the Burberry Prorsum show and also checked out Matthew Williamson's presentation.
