Hollywood actress Julianne Moore has teamed up with the Save The Children charity in a new initiative to help improve life for underprivileged kids. The Magnolia star is offering Valentines' Day cards on the Internet in return for a donation to the charity. The cards, featuring children's artwork, can be printed or emailed to loved ones. And Moore, who is mother to son Caleb, nine, and daughter Liv, five, hopes the scheme will catch on in schools where kids send each other Valentine's cards. She says, "I know my kids are very service-oriented, and they're very into the idea of charity - particularly when it comes to other kids. "It's just sort of a nice way to acknowledge kids who were struggling in America. It's like kids loving kids."
