It’s official. Nigel Lythgoe is proud to announce that Katie Holmes will grace the stage for the 100th episode of So You Think You Can Dance on July 23.

The actress will dance in a tribute to Judy Garland choreographed by Tyce Diorio. Mrs. Cruise plans to donate her entire appearance fee to the Dizzy Feet Foundation, a charity founded by Dancing With The Stars judge Carrie Ann Inaba and Hollywood producer Adam Shankman to provide scholarship opportunities for underprivileged dancers.
