Katie Holmes Gets Happy With Judy Garland

For her performance on So You Think You Can Dance, Katie Holmes will re-create Judy Garland‘s “Get Happy,” from her 1950 musical, Summer Stock.

An Us Weekly spywitness says Katie will twirl her hair and “seductively shakes her hips” in an all-black ensemble similar to Garland‘s: black velvet fedora, patent leather heels, nylon stockings, body-hugging skirt and micro-mini skirt.

Tyce Diorio choreographed the routine while the show’s producer and judge Nigel Lythgoe directed.

Katie‘s performance “might broadcast this week as news has started to leak out — but they’re trying to save it for July 8th, as that is the 100th episode.”
