Ariana Grande delivered her first musical number in Wednesday (Dec. 7) night's Hairspray Live! TV musical event as part of the ensemble number "Mama I'm a Big Girl Now," also featuring Dove Cameron and Maddie Baillio as the three young characters looking for more independence from their overbearing parents. (Grande plays Penny in the production, friend and classmate of protagonist Tracy Turnblad.)

"Mama," which first appeared in the 2002 theatrical musical, sees a return to Hairspray action after being relegated to the end credits of the 2007 film adaptation due to the difficulty of its staging.
