Gisele Bundchen: 2011 UN Flagship Environment Award Ceremony

She's been quite the busy lady as of late, and Gisele Bundchen was busy attending the UN's Flagship Environment Award ceremony in New York City on Tuesday night (May 10).

Dressed in a sexy white frock, the Brazilian supermodel posed for pictures upon arrival as she readied to tend to hosting duties at the Big Apple event.

With the event being held to recognize those making a difference on environmental issues, Gisele's hosting efforts come as she currently serves as the United Nations Environment Program’s Goodwill Ambassador.

Miss Bundchen was joined onstage to dish out commendations by fellow Goodwill Ambassador and actor Don Cheadle, with whom she's teaming up with for other upcoming World Environment Day efforts.
