Oprah has been a big fan of music legend Tina Turner for decades—she even sported Tina's signature hairstyle and danced with her on stage!

Since 1990, Tina has made 16 appearances on The Oprah Show, often times to help make viewers' wildest dreams come true. But, in January 2004, Tina turned the tables on Oprah and performed at Oprah's surprise 50th birthday bash.
