NBC's Hairspray Live! left things on a high note when it premiered on Wednesday. While there were quite a few standout performances [1] throughout the night, "You Can't Stop the Beat" definitely made us want to get up and dance. Not only did the number include some fancy choreography, but Ariana Grande [2] had a full-on diva moment as she was carried on stage and proceeded to snatch the spotlight with her killer pipes. Just further proof that she was the perfect choice for Penny [3].
