Gisele Bundchen gave birth to her second child just six months ago, but you'd never know it judging from the picture she posted on Instagram Tuesday. Motherhood clearly agrees with Tom Brady's 32-year-old supermodel spouse (right), who looks limber as she does yoga with a pal. (We're told that's a variation of the Twisting Warrior pose.) "A beautiful way to start the morning practicing with my friend Cristina Kalyani Paes," wrote Gisele. "Wishing you a joyful day!"
