Alexa Demie is an American actress and singer. She is best known for her role as Maddy Perez on the HBO teen drama television series Euphoria. Demie made her feature film debut with a minor role in the comedy-drama Brigsby Bear (2017), and went on to star in the coming-of-age film Mid90s (2018) and the drama film Waves (2019). She has also appeared in numerous music videos.
Born in Los Angeles, California, Demie grew up in the neighborhood of Atwater Village. She was raised by her mother, Rose Mendez, a make-up artist whose family immigrated to Los Angeles from Mexico when she was an infant and who got pregnant with Demie at an "extremely young" age. Demie has said that she "didn't grow up with the best male figures in [her] life" or "much respect for men". She lived in an apartment across the street from a meth lab and next door to several meth addicts, with the Black Eyed Peas recording studio being around the corner from her. According to her, there was frequent fighting and yelling in her home growing up, and she ran away from home as a teenager in order to escape her toxic family environment. However, she has described her family as "very supportive" and "there for each other". From elementary to high school, Demie was bullied by her classmates, describing herself during that time as "quite a loner". She got involved with performing arts in high school during her senior year.While in high school, she spent her spare time bedazzling sunglasses that she purchased from Downtown Los Angeles, which led to her creating Mainframe, a line of sunglasses that she began selling at a store on Melrose Avenue where her friend worked. The brand eventually became popular overseas, with Mainframe glasses being worn by G-Dragon, Jennifer Lopez, Nicki Minaj, and Amber Rose and appearing in Vogue Korea, though she soon stopped making them due to not being paid for her designs. Also in high school, she started writing songs and designed a costume for one of Minaj's first music videos. Demie had plans to become a fashion designer but after attending orientation for an art school in New York, she decided against it.
