French model Laetitia Casta
was discovered when she was 15, and soon after she became the official face of L'Oréal, Dior, and Chanel. Like many other supermodels, she's appeared in Victoria's Secret catalogues and (of course) in the Sports Illustrated Swimsuit Issue
. Three times. Now she's more into acting than modeling, but she's still repping Ralph Lauren
's latest fragrance.
