When Tina Turner embarked on her "Wildest Dreams" concert tour, Oprah Winfrey -- who proclaimed herself "the biggest Tina Turner fan there is" -- traveled with Tina from Houston to New York City. When Turner asked Winfrey to dance onstage, the usually composed talk-show host was so nervous that her knees knocked together! ("You really don't have any rhythm, do you?" Tina joked.) Oprah has said that going onstage with Turner really taught her to live in the moment. It's no coincidence that she later dubbed her wish-granting 2004 season "Wildest Dreams."
