The young actress is producing a film, recording music and dabbling in fashion.

Name: Alexa Demie

Age: 24

Hometown: Atwater Village, Calif.

Now lives: In a three-bedroom house in the San Fernando Valley section of Los Angeles, with her two dogs and a yard full of citrus and avocado trees.

Claim to fame: Ms. Demie is a singer, fashion designer and rising actress best known for “Euphoria,” on HBO, in which she plays Maddy Perez, a former pageant queenin an abusive relationship with a toxic jock named Nate Jacobs (played by Jacob Elordi).

“I use my mom for a lot of things,” said Ms. Demie, who recalled growing up in a home with nonstop screaming and fighting. “I think I feel her pain really strongly. I tell my mind I’m releasing the pain, to heal it.”

Big break: As an unknown actress in Hollywood, Ms. Demie had small guest spots in TV shows including “The OA” and “Ray Donovan.” Things took off when her producer friend Mikey Alfred put her up for a role in “Mid90s,” a coming-of-age skate film written and directed by Jonah Hill.

Next, she auditioned for the film “Never Goin’ Back” but lost out. A year later, the director of that film, Augustine Frizzell, helped her land the part of Maddy in “Euphoria.”
