What exactly is a UNICEF Goodwill Ambassador you ask? It's a celebrity who holds a large platform, and who helps raise awareness for underprivileged children. According to their website, "UNICEF’s celebrities have a wide range of talents and achievements, but they all share a commitment to improving the lives of children worldwide". Stars like Priyanka Chopra and David Beckham are just a few who have shown their commitment to this cause.
