Comedian, talk show host, American Idol judge and actress, Ellen Degeneres has established herself as one of the most successful female performers in show business. The winner of Showtime's Funniest Person in America in 1982, Degeneres was invited to guest on the Tonight Show four years later. Her career exploded as a result, including getting her own sitcom, Ellen. She made her movie debut in Conehead, but is probably best known as the short-term memory loss fish Dory in Finding Nemo. She was the fourth judge on American Idol, offering comic relief on the panel of judges in season nine.
