Sporting workout gear and carrying a water bottle, Gisele Bundchen took a solo walk along the river in Boston yesterday. Gisele had the company of her son, Benjamin, for an afternoon at the park on Wednesday. The duo ran around the sandbox and hung out on the swing set. There have been rumors that Gisele is pregnant with her second child, but she has yet to comment on the news. She is, however, speaking out about her love for the environment, and she was recently honored at an event in her home country. Gisele is representing the annual Casa Cor, which brings together fashion, design, and sustainability and continues until the end of July.
