Mamma Mia Star's Daughter: Wild Untold Story
The daughter of Mamma Mia star Amanda Seyfried is Nina Sadoski, a 9-year-old girl born on March 24, 2017, who has captured public attention for her obsession with her mother's iconic role as Sophie Sheridan in the 2008 blockbuster film.
Family Background
Amanda Seyfried, renowned for her role in the ABBA-inspired musical Mamma Mia!, shares Nina with her husband, actor Thomas Sadoski. The couple eloped in March 2017, just weeks before Nina's birth, and relocated to a 72-acre farm in New York's Catskill Mountains to raise their family away from Hollywood's glare. Seyfried has described Nina as a natural performer, often sharing glimpses of her helping with farm chores like feeding animals, as seen in a March 2022 Instagram video captioned "She's hired."
The family expanded in September 2020 with the birth of their son, Thomas "Toma" Sadoski Jr., now 5 years old. Seyfried maintains strict privacy for her children, rarely showing their faces online and stating in a 2023 Entertainment Tonight interview, "I don't share her face or anything: I'll let her choose when she wants to do that later on in life." This approach has shielded Nina from paparazzi while allowing subtle family insights through Seyfried's selective posts.

It's a bit strange, yet it's also quite beautiful." The 2008 film grossed $609.8 million worldwide, cementing its cult status.
