Short Bio About Lili Reinhart
Born Lili Pauline Reinhart on September 13, 1996, in Cleveland, Ohio, Lili grew up as the middle child in a family of three sisters. From a young age, she showed a flair for performance, landing her first acting gig at six in a local commercial. By her early teens, Lili was battling severe anxiety, which she later channeled into her advocacy work and her 2020 poetry collection, Swimming Lessons: Poems, a candid exploration of mental health and self-discovery.
Her big break came in 2017 with Riverdale, where she stepped into the wholesome yet fierce Betty Cooper, earning a Teen Choice Award and a global fanbase. Standing at 5’6.5″ with a Virgo’s precision and passion, Lili’s career has blossomed into diverse roles, including the quirky Emily in Hustlers (2019) and the introspective Rose in Chemical Hearts (2020). Off-screen, she’s an avid reader (favorites include Sylvia Plath), a makeup enthusiast with killer Halloween looks, and a close friend to co-stars like Camila Mendes. In 2023, she founded the Gurls Talk mental health initiative, empowering young women to prioritize wellness. At 29, Lili remains a relatable force, blending Hollywood glamour with grounded Midwestern roots.
