Rosie Huntington-Whiteley London - Arabstoday She's one of the most sought-after models in the world, and is under constant pressure to look good. But it seems Rosie Huntington-Whiteley has taken her desire to maintain her slim figure a bit too far, judging by photographs of the 24-year-old model at a Burberry event in Beverly Hills last night. The British model, who embarked on a strict diet and exercise regime to get in shape for her role in Transformers: Dark Of The Moon, looked noticeably thinner than she did last year. Rosie's negligee-style dress highlighted her tiny waist and skinny arms as she arrived at the Burberry store in Beverly Hills. The stunning model, who is dating Jason Statham, spoke earlier this year about how hard she works to maintain her figure. She said: 'It takes lots and lots of hard work. I have three personal trainers - James Duigan in London, Jason Walsh in Los Angeles and my friend Justin in New York. 'That means there’s no excuse not to be in the gym wherever I go.' And referring to what she eats to stay slim, Rosie said: 'Everything starts with exercise. Then you want to look after yourself and put good food in your body. 'I have a really good response when I cut out carbs so that’s something I always do before a great event. I eat a high-protein diet and lots of greens.' A spokesperson for the actress previously told MailOnline that staying healthy is a huge part of Rosie's life. She said: 'Rosie is very health conscious and always has been (her mother was a fitness instructor) and likes to eat well and keep trim.' Rosie, who is the face of the designer fragrance named Burberry Body was joined by a whole host of familiar faces at the Burberry boutique in Beverly Hills. Talking about why Rosie was named the face of Burberry Body, Chief Creative Officer Christopher Bailey said: 'Rosie's effortless style and her staggering beauty made her the natural choice as the first Burberry Body.' And Rosie added: ''It’s a huge honour to be working with Burberry again, a brand that put my career on the map and helped launch me. 'To be asked to be the first 'Burberry Body' is an amazing compliment.' The model-turned-actress is once again separated from her actor boyfriend, who lives in London, after the couple have spent most of their summer apart due to work schedules. Earlier this month the couple were seen enjoying a rare date night in the English capital heading to Nobu for dinner. But tonight it was back to work for Rosie who joined Bailey to help host the event. Guests including actress Kate Bosworth, Glee star Jayme Mays, Beyonce's sister Solange Knowles and Lily Aldridge were in attendance. While stylist Rachel Zoe, TV presenter Cat Deely as well as a number of familiar faces also attended the party.
