One source claims the 18-year-old was actually bullied for being there -- apparently not everyone thought she earned the right to walk the shows!
The insider spilled:
Earth lover Gisele Bundchen was in Rio de Janeiro today partake in some World Environment Day festivities.
The supermodel slash Goodwill Ambassador left the Copacabana Palace Hotel looking environmentally casual in a WED tee, black pants and aviators to protect her pretty little eyes from those harmful UV rays.
Gisele still hasn't confirmed if she's pregnant with baby #2 and wearing that loose of a t-shirt is only adding fuel to the fire.
