Charlize Theron: Messenger of Peace?

Joining the ranks of fellow superstars George Clooney and Michael Douglas, actress Charlize Theron became the latest A-list celeb to be named a United Nations messenger of peace.

The Aeon Flux star, 33, is now the tenth celebrity to be given the messenger of peace designation by the U.N. and she will be expected to leverage her high-wattage star power toward the goal of ending violence against women around the world.

"You have used your voice, compassion and special relationship with the public to create a better world," U.N. Secretary-General Ban Ki-moon said to Charlize during Friday's announcement.

In addition to her work on film, the South African-born star has been lauded for her efforts to bring mobile health care units to the poorer and more remote regions of her native country.
