Katie Holmes is set to vamp it up for a Judy Garland tribute performance on US talent show So You Think You Can Dance.

Tom Cruise’s wife is reportedly planning to wow TV audiences by strutting her stuff on stage in a sexy all-black ensemble during the show, hosted by British presenter Cat Deeley.

In a jaw-dropping routine, the former Dawson’s Creek actress, 30, will sing Garland’s Get Happy hit from the 1950 musical Summer Stock.

She is expected to show off her figure in an outfit similar to Garland’s famous black velvet fedora, patent leather heels, nylon stockings, body-hugging skirt and micro-mini skirt.

Holmes has reportedly been rehearsing this week at the Fox studios, in California.

A source said the Batman Begins star has been thrilling everyone with her performance

“She looks incredible. She is just doing an amazing job. Everyone is absolutely floored by how talented she is.”

The red-hot performance is expected to be shown on the primetime Fox show early next month.
