While "Dancing With the Stars" celebrated their 200th episode, they were joined by Taylor Swift, who also had a milestone achievement to celebrate tonight -- the pop-country sweetheart sold over one million copies of her album "Speak Now" in its first week on shelves.
Swift, with her sparkly guitar in hand, sang her newest single, "Mine," while some of the pros performed a beautiful routine. Later, she sang "White Horse" from her last record, "Fearless." The song was accompanied by a montage of favorite moments from previous seasons - and punctuated by a starstruck Tom Bergeron "fainting," in homage to Marie Osmond's collapse during her run on the show.
Rod Stewart also took to the stage, and later in the evening, basketball player and TV personality Rick Fox was eliminated despite his well-received quickstep this week.
