The actress performed as her "Glee" character, sharp-tongued cheerleading coach Sue Sylvester, in a music video homage to Madonna's "Vogue" on Tuesday's episode.
The music video was a tease for next week's all-Madonna episode, which will feature songs including "Like a Virgin," "Open Your Heart" and "Express Yourself."
Lynch glammed it up in the black and white video, recreating outfits and choreography from Madonna's original 1990 "Vogue" video, including the pop star's infamous cone bra.
A few lines of the song were adapted to include Sylvester and her McKinley High School rival, glee club advisor Will Schuester.
"Gene Kelly, Fred Astaire. Sue Sylvester, dance on air...Lauren, Katherine, Lana too. Will Schuester, I hate you," she sings.
"Glee" co-stars Amber Riley and Chris Colfer also starred in the video.
