However, in a new interview with Business of Fashion, Selena admits that she doesn't have great memories about her time as Alex Russo on Wizards of Waverly Place.
"I started getting known for things that weren't [related to] my work," she recalled. "That's when my passion started to really feel like it was going further and further away. And that scared me."
"When I got older, I started to become exposed to the truth behind some stuff and that's when it flipped a little bit.
"I realised that, 'Oh this is actually really hard, and kind of slimy in certain areas,'" Selena continued, "and I didn't realise that certain people wanted certain things from me. My confidence went through a lot with that."
A turning point for Sel was when she was photographed on the beach.
"I remember just feeling really violated when I was younger, even just being on the beach," she said. "I was maybe 15 or 16 and people were taking pictures—photographers."
She added, "I don't think anyone really knew who I was. But I felt very violated and I didn't like it or understand it, and that felt very weird, because I was a young girl and they were grown men. I didn't like that feeling."
Selena turned 18 and was still playing Alex Russo on the show, but it was then that things started to change for her.
"I was probably 18-years-old, is when I felt like the flip happened. I didn't feel like it was about my art as much.
"I was on the fourth season of the show, and I felt like I was outgrowing it," she said. "I wanted something different and obviously, I fell in love [with then-boyfriend Justin Bieber] for the first time. There was all this stuff that was happening, and I didn't know what to do."
We all remember that time of her life, as it's basically still being brought up by fans on a daily basis.
In 2012, Selena took a break from music, then again during her cancelled Revival world tour in 2016.
"I would look at myself in the mirror and I just felt like, 'I've had enough, I don't know if I can go on anymore,'" Sel explained. "And I stopped it for a second. But it didn't mean that I didn't love it, I just had to find what I was going to do with it. As long as I'm healthy and happy in my mind, I'm all about it."
