Noah's older sister, Taylor, is 25 years old — and it was actually Taylor's dream to become a model as a child that led to Noah's acting career. 

When Noah was 8, he was dragged along to attend an open call audition with his sister at a talent agency South Florida. "I'm sitting there and someone comes over to me and they're like, 'Hey, are you auditioning?' and I was like, 'No!'" Noah told Pop-Culturist in 2017. "And they said, 'No, I really think that you have potential, you should audition.'" 

"Somehow I made it onto a show and then another show and now I'm doing my thing, so how did I start?" Centineo told the publication. "Because my sister wanted to be a model and I was dragged along to support her!"

Spoiler alert: Noah wound up signing with the agency and began landing gigs. Ultimately, he and his family relocated to Los Angeles when Noah was 15 to pursue acting. At the time, he had told his parents, "This is what I want to do. If you move me out, I swear I will make it," according to the Los Angeles Times.
