WATCH: Kate Hudson's Sizzling Performance on 'Glee'

Kate Hudson is muy caliente on Glee! The sexy actress, who plays Rachel Berry's New York City dance instructor in the fourth season of the hit show, shows off her moves in a new clip Fox has released.

The mashup of Lady Gaga's "Americano" and Jennifer Lopez's "Dance Again" features Hudson (who previously proved her triple threat skills in the musical feature Nine) shimmying around in a class (and attempting to sing in Spanish) full of willing students, except for Berry (Lea Michele) who looks on anxiously as everyone writhes around to the music.

As for her character -- Cassandra July -- the producers say she's definitely going to spice up the season.

"She's hard-ass," co-creator Brad Falchuk said of the role. "And she has her own demons." 

Get ready Gleeks, because Hudson, 33, has gone on record describing July as "nasty."

"[She’s] a really nasty, fun character," Hudson told Access Hollywood at the Toronto International Film Festival, where she was promoting her upcoming film, Reluctant Fundamentalist.

Despite rumors that Hudson thought Michele was a diva on the set, the Oscar-nominated actress says she had a great time working with the Glee cast.

"She is definitely very petty and fun, but she’s got a good arc. She goes somewhere," Kate hinted. "But, it’s a blast. I’m having so much fun on Glee. It’s really, really fun."

Watch the clip!


Glee returns to primetime Thursday (9 p.m. ET on Fox).
