Supermodel Gisele Bundchen stayed so thin while pregnant with baby Benjamin, she didn't need to wear maternity clothes.
"I kept myself in good shape throughout the pregnancy, feeding on a healthy diet, meditating and doing exercises such as yoga and kung-fu," she told Brazilian newspaper Folha de Sao Paulo Veja (as translated by New York magazine).

Continued Bundchen, 29, "I gained a little, but I kept using almost the same clothes, with minor adjustments to close in the belly."
Since welcoming her first child with husband Tom Brady, Bundchen admits, "I have not had time to return to exercise. In the first months it's all about the baby.

"But little by little I recovered the form," continues the mom -- who posed for Brazilian fashion line Colcci just six-and-a-half weeks after giving birth. "It helps that I have not gained much, have had natural childbirth and breastfeeding."
Bundchen also says she doesn't have any help raising her son, whom she gave birth to in a bathtub in Boston. (Brady is also dad to Jack, 2, with ex girlfriend Bridget Moynahan.)
"At the moment I have no nanny, but my mother stayed with me since before the birth of Benjamin," she says. "I could not ask God for better support than this."
Her only difficulty so far? Getting her beauty rest.
"I have not slept much. In these first months, the baby usually nurses every two hours or three hours," she says. "It is quite tiring, but it is such a special moment, I'm enjoying it the most. I have dedicated my time entirely to him."
