United Nations Goodwill Ambassador Nicole Kidman spoke yesterday at UN headquarters in New York, saying being a mother motivates her to fight violence against women.

A seven months' pregnant Kidman launched a web site petition yesterday as part of the "Say No to Violence Against Women" campaign.

“I’m a mother, I have a child on the way, I have two children in the world and a lot of (my motivation) is about realizing the things that are wrong and how can I contribute,” she said during the press conference.

Good for you for giving back, Nic!
