From Wiki:
Karolína Isela Kurková (born February 28, 1984) is a Czech
supermodel, best known as one of the Victoria's Secret Angels.
Mario Testino said of Kurková, "The proportions of her body and her
face, as well as her energy level, make her a model who could fit
almost into any moment." Designer Marc Jacobs said, "She has an
angelic look with a dark side, she's sweet and fun but looks like
she could be an evil bewitching child." Vogue editor Anna Wintour
called her the "next supermodel".
