Russian beauty Natalia Vodianova has landed not one, not two, but three Spring 2010 campaigns. She will be the new face of Yves Saint Laurent (dethroning Christy Turlington), Givenchy and Stella McCartney. She will also continue her contracts with Guerlain, Etam lingerie and Calvin Klein perfumes. Oh, and she's only 27 years old and a mother-of-three. Now, all of that is some super-model math.
