Former model Cindy Crawford might be 41 but she can still make heads turn by her fab figure.

The supermodel's sexy body was revealed in St Tropez's beaches pics where she was holidaying with hubby Rande Gerber.

As for what is the secret behind Crawford's svelte figure, nutritionist Juliette Kellow believe it was healthy food and exercise.

"Women are more aware about the importance of healthy eating and exercise, so we're all looking younger and fitter," the Mirror quoted Kellow, as saying.

"Celebrities like Cindy are great role models for showing you don't have to go under the knife to look fantastic in middle age," she said.

The dietician insisted that the celeb was a role model for women.

"Women in their 40s now go out on the town as they did two decades ago. They see people like Cindy and are inspired," she said.
