The roles are not the first time Sweeney has helped her family.

In December, the Emmy-nominated "Euphoria" and "The White Lotus" star revealed during an appearance on "The Kelly Clarkson Show" that she bought back her family's generational home.

"My great-grandma had this beautiful house; it was a two-bedroom cute house that they lived in. My grandma was born in it. My mom was born in it, and then as the kids got older, they built on the property another home," Sweeney told Clarkson. "And when my great-grandpa passed away and my great-grandma got old they just couldn’t afford to keep it anymore."

Sweeney, who is from a town near Spokane, Washington, decided to purchase back the family home in 2022.

"I called up the owners and I said, 'I want to buy my great-grandmother’s house back,'" Sweeney said. "My (grandma) still lives in the house next door," she added. "So I'm neighbors with my (grandma) now."
