The 40-year-old Australian actress, Rebel Wilson, appeared on "Who Wants to Be a Millionnaire" and was raising money for the charity of her choice -- School of St. Jude in Arusha, Tanzania. Rebel served as an ambassador and once sponsored a student. She won a total of $250,000 and donated her entire winnings to the School of St. Jude. Very exciting news for St. Judes.
