Riverdale was obviously Reinhart's breakout role, but the actress is upfront about how long it took her to really "make it" in the business. As she explained to V Magazine, Reinhart has been working since she was a kid, when the actress first started booking roles in plays around her hometown.

"I was like, well, this is something I wanna do. I was always a performer kid, like annoyingly so. I would put on shows for my family and direct my friends in little plays, and my little sister, I'd make up dances with her. But when I was 12, that was when I started taking it seriously, and my mom, for some reason, believed in me and helped me find an agent," she advised.

Reinhart's parents supported her 100 percent, even driving her eight hours to New York for auditions. But it's been an uphill battle, and the Riverdale star holds no illusions about that fact. "It definitely didn't happen overnight. They kind of make it seem like, "And just like that, she got her big break." I've been working at this since I was 12, so it's been a journey," she said.
