The queen of the catwalk is officially hanging up her heels. Gisele Bundchen, perhaps the gold standard on the catwalk, is saying goodbye to the runway after 20 years. The supermodel announced that her final runway walk will be at the Colcci show during São Paulo Fashion Week in April 2015. Considering Gisele is Brazilian, it's a fitting end to a decorated runway career. Gisele, 34, will continue to model, but will no long strut her stuff on the long catwalks of the fashion world. According to Forbes magazine, she is also the world's first and only billionaire model.
