But the 19-year-old confesses she was actually miserable while working on set due to a nasty coworker.
"I worked with someone who told me they'd never like me," she explains in the August issue of Seventeen magazine. "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."
However, Ariana is now happier than ever starring on Sam & Cat, a new series, and is hard at work on her first album. "The Way" singer has been working on it for more than three years!
"I'm a big perfectionist!" she explains. "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."
You go, girl!
UPDATE: Ariana later clarified her comments in a statement to Seventeen, saying: "My years filming Victorious were some of the HAPPIEST of my life and that cast is family to me. The stories I shared with Seventeen were actually reflective of a different work experience."
