Gisele Bundchen & Her Smiling Boys Enjoy A Day At The Park [PHOTOS]

Someone looked like they were having fun despite the chilly temperatures!

Gisele Bundchen played with her two-year-old son Benjamin and stepson John at a local park in Boston, MA today. The supermodel had a big smile on her face as she and the nanny pushed the boys on the swings and enjoyed some fun on the slide.

Bundchen has been named the most eco-friendly celebrity at the annual Green awards in London. The Brazilian beauty, currently involved in several environmental campaigns and a goodwill ambassador for the United Nations’ environment program, is helping to launch safe water initiatives and anti-foresting movements.

And her good work was celebrated at the awards ceremony last week when she was honored as the best green international celebrity.
