Katie Holmes' Leggy Judy Garland Dance (VIDEO)

Katie Holmes performed a tribute to Judy Garland on the 100th episode of So You Think You Can Dance Thursday night.

Holmes, 30, danced to and sang Garland's classic "Get Happy" in a tux jacket and tights to promote her Dizzy Feet Foundation, which provide scholarships and assistance to kids who want to become professional dancers and will also help dance instruction nationwide.

The dance starts after 2 minutes.
