After more than two hours of a star-studded live television broadcast of Hairspray, the musical came to a close on the signature number "You Can't Stop The Beat." And with the way the cast -- featuring Ariana Grande, Derek Hough and Jennifer Hudson -- performed the closing song, there really was no stopping the beat.

The tune began with Tracy (Maddie Baillio) and Link (Garrett Clayton) dueting, with Penny (Grande) and Seaweed (Ephraim Sykes) joining in soon after and making for a spot-on lovebirds jam session.

Once Tracy booted out Amber (Dove Cameron) as the newly crowned Miss Teenage Hairspray, the whole gang (sans the bitter Amber and her mom Velma [Kristin Chenoweth]) joined in, making for the perfect ending of an overall applause-worthy show.
