The actress will play Lea Michele's dance instructor Cassandra July in the upcoming series four of the show - and will reportedly appear in as many as six episodes.
The blink-and-you'll-miss-it clip shows Kate Hudson rocking a seriously skimpy black leotard, heels and fishnet tights to take to the dance floor in front of her students.
Stalking around the room the actress promises to 'outdone' any of her students up for the challenge - but it seems Lea Michelle's character, Rachel Berry, is not!
We can't wait to see how that turns out!
Lea previously gushed that she couldn't wait to work with Kate, telling ET Canada at Comic-Con: 'I am so excited! Oh my God! I’m so obsessed with her,' she admitted.
Not as excited as us!
