Gisele Bundchen brought her young son, Benjamin Brady, along to play at a Boston park this morning. Benjamin nearly got himself there on a little bike. Gisele's home in Massachusetts following a work adventure to Brazil this week. She launched Top Cufa's model search in her home country and spent a morning at the Green Nation Fest at Quinta da Boa Vista public park, planting the first of thousands of new trees that will grow in a degraded region. Gisele's busy trip came amid rumors that she and husband Tom Brady are adding to their family. Benjamin and his brother, Jack Moynahan, may welcome a sibling in the coming months if rumors that Gisele is pregnant again are true.
