Over the past six months we've all sat back in awe to see how Gisele Bunchen completely snapped back into shape after giving birth to son Benjamin. As if we didn't know it already, she confirmed just how in shape she is when she hit the runway at Sao Paulo Fashion Week for Colcci this week. Bunchen sported three looks in the show, walking the finale with the designer. "I was very nervous . . . but I'm very happy, everything went right," she told Brazillian newspaper Estado de Sao Paulo.
