Pop’s newly inaugurated princess is trying Broadway- joining NBC’s Hairspray Live! as Penny, played first by Amanda Bynes in the 2007 movie. Grande is arguably the most relevant name to sign on to a NBC live musical. She’s got legions of tweens that will scream when her face appears on TV December 7th. NBC is probably incredibly excited to add her name to ads. Grande tweeted earlier today that she’s never been more excited in her life.
