She began: "I signed my life away to Disney at a very young age and I didn't know what I was doing."
Speaking about her latest role as Mabel Mora in the Hulu comedy Only Murders in the Building, Gomez told reporters at the TCA Summer 2021 Tour press conference: "What I'd say is the level of sophistication of the material is the first reason why I wanted to do this.
"I didn't know what I was doing. I was just running around on set."
It marks her first TV role since Wizards of Waverly Place concluded in 2012, and she relished playing someone her age.
She said: "It's really nice to be back on TV and it's nice to be cast as my actual age, which never happens.
"I don't know if I'm a good actor. I just do my job."
The Lose You To Love Me singer previously revealed she was bullied during her time at the Disney Channel.
She said in 2017: "I think he understood that I knew what it meant to be bullied. I went to the biggest high school in the world, which is the Disney Channel. And my mum had a lot of history dealing with [bullying]. I heard her stories growing up. She's very open about it."
Her mother Mandy added in the joint interview: "When I was growing up, I was always bullied because I was the outsider, the weird girl with the purple hair and combat boots. Then I was a teen mum. You get really judged. I had counsellors telling me how I'd ruined my life, [Selena's] life and how I ruined the father's life, even though he participated."
