Katie tapped for ‘Dance’

So Katie Holmes thinks she can dance – and next week, she’ll display her moves before a discriminating audience.

The 30-year-old actress will perform for the 100th episode of Fox’s “So You Think You Can Dance,” airing Thursday.

Holmes will pay homage to Judy Garland. In a taped number, she’ll sing and dance to the Garland classic “Get Happy.”

Her TV cameo is meant to promote the new foundation she launched with “Dance” producer Nigel Lythgoe and “Dancing With the Stars” judge Carrie Ann Inaba.

The nonprofit, called Dizzy Feet, aims to support dance education and programs, and talented dancers who can’t afford training.

Norsemen and Portman

“Star Wars” co-star Natalie Portman is storming back into action films with a role in the comic-book adaptation “Thor.”

The 28-year-old Portman has been cast as Jane Foster, who was a nurse and first love of the title character in the Marvel Comics.

According to Marvel Studios, the character is being updated for the movie version of “Thor,” in which the Norse warrior is cast down to Earth to live among humans. It’s due to hit theaters in May 2011.

Fox back in the hunt

Actress Jorja Fox, who left the CBS crime drama as a regular two years ago, will return as Sara for the 10th-season debut and other episodes, the network said Friday.
