Lili Reinhart had a pretty impressive acting resume before she was even out of her teens, appearing in everything from sitcoms to horror films. That's because she got a strikingly early start on her career. Reinhart was born on September 13, 1996 in Cleveland, Ohio, and she trained as an actor, dancer, and singer from childhood. She had an agent by the time she was 11 years old, and regularly took the trip from the Midwest to New York City to take part in auditions. After appearing in a couple of short films, Reinhart got her first high-profile credit in 2011 with an appearance on "Law & Order: Special Victims Unit" (NBC 1999- ). That same year, Reinhart was seen in her first feature film, the horror flick "Lilith" (2011). After working in a few more films, including "The Kings of Summer" (2014) and "Forever's End" (2014), Reinhart earned her first recurring role, playing the part of Heather in the sitcom "Surviving Jack" (Fox 2014), which starred Christopher Meloni. But something bigger still lay ahead for Reinhart; she nabbed the part of Betty Cooper in the teen drama series "Riverdale" (CW 2017- ), a show seeking to subvert and reinvent the characters the world had come to love through "Archie" comics. Like the rest of the iconic figures in the series, the live-action version of Betty ended up being a very different sort of character from the one that was depicted in the comics.
