When Oprah found out that Desperate Housewives star Felicity Huffman's wildest dream was to be a backup singer, the wildest dream machine went to work! After all, Oprah had some experience backing up the best, so she knew exactly who to call. When the backup gig was set, Oprah secretly showed up on the set of Desperate Housewives to surprise this unsuspecting star.

Oprah: I've got you a gig as a backup singer. You're going to come to Chicago, and you're going to be a backup singer to the one and only Tina Turner.

Felicity: Oh my God! No…I'm such a loser!

Oprah: No. You're gonna be hot. It's gonna be hot. You'll have the most fun. I did it once and it was the most fun. I haven't had so much fun until today. You and Tina Turner.
