Gisele Bündchen is already back at work, less than two months after the birth of her first child, Benjamin, in December. Gisele, who calls her newborn son "a little angel," says she’s not using nannies to help her out, but is instead relying on her family. She says her mom, Vania, watched the infant while she did a modeling shoot in Brazil — just six weeks after the delivery! Gisele says the secret to losing the baby weight was being healthy while she was expecting: “I kept myself in good shape during the whole pregnancy, eating healthily, meditating and doing exercises," Gisele told Brazil's Folha de São Paulo newspaper.
