UPDATE: It’s being reported that Katie Holmes will be doing a Judy Garland tribute.

She went from acting on the stage to doing a cabaret-esque number on Eli Stone. Now Katie Holmes is prepping to kick things up a notch.

According to multiple sources, the actress has been in secret rehearsals for an appearance on So You Think You Can Dance. Why Holmes? That part is not entirely clear. (Her Broadway stint didn’t exactly involve song or dance.) But it’s rumored that Katie may be one of several special guests turning up on the program’s 100th episode.

Although Nigel Lythgoe has confirmed meeting with the Mad Money star, he has not elaborated on what the one-on-one was about. Those in the know claim Katie has been privately “working with the choreographer Tyce Diorio” for a long time now. “She looks incredible. She is just doing an amazing job. Everyone is absolutely floored by how talented she is,” a source stated.

If all goes as (reportedly) planned, be sure to tune on July 8th.
