See how Nicole Kidman, Reese Witherspoon and other Hollywood stars looked huge, flabby, and imperfect when placed next to the stunning Duchess.

During the short 3-day stay of the Royal Couple in Hollywood, Duchess Kate proved to be the only deserving princess as stars looked "unpolished" when photographed next to her. During the BAFTA Brits To Watch event last Saturday, Kate was photographed talking to Nicole Kidman, an actress who's usually noted as one of the most slender, slimmest stars of today. Standing next to the Duchess made the actress look flabby and old. In the photo, Nicole Kidman's tummy is sticking out against Kate's flat and tiny waist, not to mention Kidman's arms look like a pair of logs when placed next to Catherine's toned arms.

In a separate event, the Duchess greeted other stars during the Tusk Trust's U.S. Patron's Circle in Beverly Hills, including Reese Witherspoon. In a photograph by Reuters, Witherspoon wore a red playsuit that seems to have added a few pounds to her usually slim weight. Standing next to Catherine made Witherspoon look like a miniature lady struggling with baby fat.

Fashion expert Plum Sykes shares his two cents on Kate's slender body against the Hollywood stars. "It's not necessarily that she is too thin - and I don't think she is - it's that expensive, well-cut clothes make you look taller and thinner", says Sykes in a post by The Daily Mail. Plum Sykes is the contributing editor of the highly-celebrated Vogue U.S. It was also said that the Duchess didn't bring a stylist or dresser with her during the North American tour because according to her, it is "not necessary" and a "waste of money".

Given the freedom to wear anything she wants, the Duchess is quickly becoming Britain's most influential fashion icon and everybody is on the lookout for her clothes. All the clothes she wore during the Canadian tour already sold out on stores, including the Whistles white pleated skirt she wore on their last day.
