Gisele Bundchen gave birth in a bathtub.

The Brazilian supermodel delivered son Benjamin while submerged in water at the Beacon Hill Penthouse, in Boston, which she shares with her American football star husband Tom Brady.

She told Brazilian magazine Fantastico: "I gave birth in the bathtub."

Gisele delivered the tot on December 3 2009 and just weeks later the catwalk beauty has regained her incredible figure.

The publication reports: "Gisele gives off simplicity, spirituality and shows that she is concerned with living well, being happy and, now, with being an excellent mom. She is in shape as always, weeks after the birth of her baby."

It was recently reported that Gisele, 29, was planning to cut back on her modelling work so she can focus on being a good mother and wife to Benjamin and Tom, 32, respectively.

A source said: "With the exception of her few contracts, she's definitely taking a break. Why not? She has tons of money and a rich, gorgeous husband she adores and she wants a large family and more children."
