For the first time in the history of the U.S. franchise, celebrities playing on "Millionaire" can invite a guest to help them answer questions. It could be a relative, a beloved teacher or a famed trivia expert – anyone they want – to help them win as much money as they can for the charity of their choice. Additionally, this special run of shows will be introducing a new lifeline, Ask the Host, and a revolutionary, live, play-along app which will allow America to compete to win the same amount of money that celebrities are playing for on the show.
