NBC offers a sneak peek at its upcoming live musical with a new promo for "Hairspray Live!", just two weeks before its airing. In the approximately-30-second snippet, we get to see glimpses of the performances.

Maddie Baillios' Tracy Turnblad joins Ariana Grande's Penny Pingleton on the dance floor and shares a smooch with Garrett Clayton's Link Larkin. Derek Hough also shows his dance moves as he plays Corny Collins, the host of the dance show.

Based on the 2002 Broadway musical of the same name, "Hairspray Live!" follows Tracy Turnblad, a teenager whose dream is to dance on "The Corny Collins Show", a local TV program. When, against all odds, Tracy wins a role on the show, she becomes a celebrity overnight and meets a colorful array of characters, including Link, the resident dreamboat; Amber, the ambitious mean girl; Seaweed, an African-American boy she meets in detention; and his mother, Motormouth Maybelle, owner of a local record store. Tracy's mother is the indomitable Edna Turnblad, and she eventually encourages Tracy on her campaign to integrate the all-white "Corny Collins Show".

Joining the cast are Harvey Fierstein as Tracy's mother Edna, Jennifer Hudson as celebrity disk jockey Motormouth Maybelle, Kristin Chenoweth as villainous producer Velma Von Tussle, Martin Short as joke-shop owner Wilbur Turnblad, and Dove Cameron as dancer-slash-mean girl Amber Von Tussle.

Directed by Kenny Leon and Alex Rudzinski, it will be filmed in Los Angeles and air Wednesday, December 7 at 8 P.M. ET.
