I was fully prepared to mock Katie Holmes for the interview she gave about her upcoming, pretaped appearance on So You Think You Can Dance? Not only is Katie dancing… she’s also singing. Not only is she singing… she’s singing a Judy Garland song, just like Tom “I Love Me Some Judy” Cruise wanted her to do. But now I’m thinking twice about the mockery, because it seems Katie got involved with this whole project because she’s involved with the Dizzy Feet Foundation, a nonprofit that “provides assistance to talented underprivileged youth.”

She must have taped this thing weeks ago, when she was making zombie-like appearances all around Los Angeles. I think she also pre-taped all of the interviews about her appearance too, because she’s working in Australia now, I can’t see her flying in to LA just to promote an appearance on So You Think You Can Dance?

Katie Holmes says she is “very excited” about her upcoming singing and dancing homage to Judy Garland, airing on the 100th episode of So you Think You Can Dance Thursday.

“I like to sing and dance so it is really fun,” she tells Entertainment Tonight.

As Usmagazine.com previously reported, Holmes will dance and sing to Garland’s “Get Happy” from the 1950s musical Summer Stock, wearing an all-black ensemble similar to one Garland once wore.

At one point in the routine, Holmes – who also prances around in a black velvet fedora, nylon stockings and body-hugging skirt – is lifted over three dancers’ heads. For her finish, she tosses her fedora in the air, and one of the other male dancers catches it.

The spot is directed by show producer and judge Nigel Lythgoe and is choreographed by pal Tyce Diorio.

Holmes agreed to the dance after becoming involved with the non-profit Dizzy Feet Foundation, which provides assistance to talented underprivileged youth.

“It is to give scholarships to these young kids,” Holmes tells ET. “I think it is important to experience music and dancing and singing and the arts and sports. This is the next generation. I think it is important to give them every opportunity to grow and discover what it is that they like and to have access to the best. “

Alright, I’m officially giving her a pass on this one. No mocking. Even though she’s going to murder Judy’s — no, I won’t go there. It’s nice that Katie is drawing attention to the foundation’s work. Zipping my lips now.

On what might turn out to be a completely unrelated note, did everyone else think this blind item was about Katie and Tom? From Blind Goosip:

The attorneys have finally hammered out an agreement! We’re finally getting close to the announcement of a split of this couple. Have you noticed how few photos there have been of them together lately? Half this couple is on a project that requires travel. The other half joins them fairly frequently, but it’s really just for the sake of the child/ren. They both have outside relationships. He has a new – albeit temporary – boy toy that his boyfriend is not too happy about. She has an extra man in her life but is afraid to be seen with him before the announcement. No need to feel bad for her, though. She is will be doing a happy dance soon enough. Dance, girl, dance!

The “dance, girl” part made me think of Katie. And then I thought of Judy. And then I thought of Tom Cruise. And then… I thought of barley water. So I’m assuming “barley water” is the answer to this blind item.
