Rumors of actress Katie Holmes coming to So You Think You Can Dance (for whatever reason) this season have repeatedly appeared in the media.

Star choreographer Shane Sparks was asked about Katie's appearance on the hit Fox summer dance series, and he actually dished. Sort of.

"Katie Holmes on the show? If she can dance it would be hot," he said.

"She looks like she could get down. I think it would be dope to have more celebs on - we should have a celebrity So You Think You Can Dance!"

Celebrity So You Think You Can Dance sort of already exists, and it sort of goes by the name of Dancing With the Stars, but Shane's point is taken.

As for Katie and her mystery appearance, she will be doing a version of Judy Garland's song "Get Happy," choreographed by Tyce Diorio and directed by So You Think You Can Dance judge and producer Nigel Lythgoe.

The performance, it's been speculated, may air as early as tonight! More importantly, which pair of this season's dancers will be hitting the highway after the votes are tallied? Tune in and find out!
