Ariana Grande is going to be in NBC's Hairspray Live! She will be playing Penny Pingleton. The cast has just recently started rehearsing and they said it has been going very well. Hairspray is one of my favorite movies. I cannot wait to see Ariana Grande and other guest stars in it. The soundtrack is going to sound amazing with all the talented stars voices. I am very excited to see Hairspray Live! I wish it was a lot closer than December. Tune in to see Hairspray Live on December 7th, 2016. It's going to be brilliant.
