Katie Holmes performed a song/dance tribute to entertainment legend Judy Garland on Thursday night’s So You Think You Can Dance 100th Episode Special.

We can’t wait to hear your thoughts on the performance!!

Katie’s taped segment aired near the end of the show — she said her reason for doing the show was to introduce the new Dizzy Feet Foundation to the world. The charity, which she co-founded alongside SYTYCD judge Nigel Lythgoe, director Adam Shankman and Carrie Ann Inaba of Dancing With the Stars — is aimed at helping underprivileged youths become professional dancers. The group also provides scholarships to dancers, choreographers and dance teachers.

“I think it’s important to let kids experience music and dancing and singing and the arts and also sports,” she said.

“I want to thank Katie Holmes for working so hard on that routine,” Nigel said following Katie’s dance.
