Liz Gillies needed Ariana Grande's "blessing" before she returned to Broadway.
The 31-year-old actress first worked with 'Wicked' star Ariana on the musical '13' before they found further fame together on the Nickelodeon sitcom 'Victorious' but needed to consult her former co-star before she could commit to the role of Audrey in a revival of 'Little Shop of Horrors'.
