It has just been announced that Katie Holmes will be performing on So You Think You Can Dance for the show’s 100th episode, which will honor Judy Garland.

Holmes has been rehearsing late into the night for her dance routine, which airs on Fox on July 23rd. She’s being trained by friend and choreographer Tyce Dioro. Her costume for the dance number is inspired by a Judy Garland song called “Get Happy.”

Says executive producer of So You Think You Can Dance, Nigel Lythgoe:

“She absolutely adores dancing as does her daughter.”

Lythgoe reports that Katie and three-year-old daughter Suri have been attending dress rehearsals for the show over the past two years.

Husband Tom Cruise is often seen on set with their daughter, supporting Katie in this endeavor.

“It was great to see the sort of family bond,” Lythgoe says. “It was beautiful to see!” Adds Lythgoe: “It was the pride in Tom’s eyes, which I liked. I think we all stood around and felt very proud.”

As controlling as Tom Cruise is, I’m shocked he “allowed” Katie to do this. Seems like he wants her to be a good little wife while he’s the one bringing home the bacon. Let’s hope Katie is finally growing a backbone and doing what she wants with her career, rather than whatCruise tells her to do.
