While she is now best known for being both an iconic popstar and an Oscar-nominated actor for her performance as Glinda in Wicked, Ariana actually started out on the stage.
She got her big break in 13: The Musical back in 2008, when she was 14 years old.
Ariana then enjoyed TV success on the Nickelodeon shows Victorious and Sam & Cat between 2010 and 2014.
And before all of that, Ariana was an active member of her local community theater, and during an appearance on Jimmy Kimmel Live this week, she explained that this meant her mom was an active participant, too.
