Katie Holmes is back and she is one hot mama! She performed Judy Garland’s classic “Get Happy” on the 100th episode of “So You Think You Can Dance” last night.

Katie’s performance was in support of the Dizzy Feet Foundation, in which she’s one of the founding members. The charity provides scholarships and assistance to underpriveledged youths to help them become pro dancers.

I have to say that its nice to see Katie having some fun, so many pictures recently have showed a very tired and washed out version of her former self.
