Kate Hudson already got her dance on in the movie musical Nine, and it looks like she’ll be returning to those sexy moves on the Sept. 13 premiere of Glee, based on this exclusive EW image (co-creator Ryan Murphy tweeted a different image yesterday). Hudson plays Cassandra July, a dance instructor at Rachel’s new school, NYADA. See the larger version below…

In this scene, her first big number on the Fox hit, Cassandra shows Rachel (Lea Michele, not seen) how it’s done at NYADA. But don’t expect the pair to be bonding too much during office hours — Hudson, known for her sunnier roles, is playing kind of a witch. “She’s hard-ass,” says Glee co-creator Brad Falchuk. “And she has her own demons. She works by negative.”

Hudson has signed on for six-episodes in season 4 while fellow actress Sarah Jessica Parker will make her debut in the third episode of Glee‘s fourth season.
