Editor's Note: In an American Morning original series, "Big Stars, Big Giving," CNN National Correspondent Alina Cho looks at celebrity philanthropy and how these big stars can make a big impact. Through one-on-one interviews with Nicole Kidman, Halle Berry, Edward Norton, Julianne Moore and Justin Bieber, she shares what causes have become their passions, and how you can get involved. The one-hour special debuts December 24th and airs again on December 25th.
Nicole Kidman is a longtime goodwill ambassador for UNIFEM, the United Nations arm that fights for gender equality and to end violence against women.
Kidman was moved to act after her mother heard a report on the radio about a UNIFEM program in Cambodia. She says she was raised to be a feminist.
"A lot of my life, I've been trying to please my mother," she says. "This is probably the thing she most responds to in my life."
