Ariana Grande: I Was 'So Unhappy' Filming 'Victorious'

Ariana Grande is super smiley on the cover of Seventeen magazine’s August 2013 issue, on newsstands July 2.

Here’s what the 19-year-old entertainer had to share with the mag:

On working on her album for three years: “I’m a big perfectionist! I’m trying to channel super-confident women like Alicia Keys, Mariah Carey and Beyonce, because I realized that if you want something, you really have to go for it, just like they do.”

On not enjoying filming Victorious: “I worked with someone who told me they’d never like me. But for some reason, I just felt like I needed her approval. So I started changing myself to please her. It made me stop being social and friendly. I was so unhappy.”
