The 38-year-old actress, who has Charlotte, five, and Rocky, two, with husband Freddie Prinze Jr, is working with a charity organisation No Kid Hungry, which aims to end childhood hunger in America, reported People magazine.
"I really looked for something that I could do on a local and national level that involved children, and also some place that I could introduce my children to social awareness.
