Gisele Bundchen attended an event in her home country of Brazil today to promote the launch of Top Cufa's model search. Reportedly pregnant Gisele shared stories and chatted with the women hoping to follow in her famous footsteps, saying, "It's an honor to be invited as the mentor of the project. I feel very privileged." Gisele's trip to Rio comes on the heels of yesterday's public appearances in the city. Gisele planted new trees at a park dedication then changed into more formal attire for the UN environmental award Champions of the Earth. While she's doing her part to better the planet and mentor young girls, Tom Brady's been doing his own philanthropic work back in the States. Tom attended a charity event over the weekend and also biked through New England from Boston to Hyannis Port on behalf of his Best Buddies organization.
