Ian Somerhalder Named United Nations Ambassador for World Environment Day

Ian Somerhalder might take on the role of Christian Grey in the movie adaption of 50 Shades of Grey.

But he's definitely been named United Nations Ambassador for World Environment Day, an event led last year by Gisele Bundchen and Don Cheadle, who teamed up to encourage folks around the world to mobilize their efforts, register their activities and set a record for clean-up efforts.

"We're all working together," Somerhalder says in the following video, joking that he "couldn't decide between Team Don and Team Gisele," so now he can assist both while promoting a great cause.

Somerhalder, of course, is best known as Damon Salvatore on The Vampire Diaries.

But he's proven time and again - actually testifying in front of Congress last year - that he's a lot more than a pretty face.
