How Old Is Amanda Seyfried's Son? Meet Nina & Thomas Jr. (2026)

The Direct Answer: How Old Are Amanda Seyfried's Kids?

The answer to 'how old is Amanda Seyfried's son": Thomas Sadoski Jr. is 6 as of October 2026. His older sister Nina is 9.

Nina Sadoski (Age 9)

Nina Sadoski was born in March 2017, shortly after her parents' secret elopement that same month. She is 9 years old as of October 2026.

Nina arrived at the very start of her parents' marriage — Seyfried and Sadoski eloped in March 2017 with only an officiant (and, famously, Seyfried's dog Finn) present, and their daughter followed within weeks. Like her brother, Nina has been raised largely away from the Hollywood spotlight on the family's farm in upstate New York's Catskill Mountains, which Seyfried bought in 2013.

Seyfried has occasionally shared glimpses of Nina's life — her playful spirit and love of fashion — while keeping her daughter's face and daily life private. In a Net-a-Porter interview, Seyfried described the farm arrangement: "It's way less Hollywood noise... [My children] know that they're safe at home and have their own privacy — and that's everything.'

Nina's birth in March 2017 came within weeks of the secret elopement — the couple married and became parents almost simultaneously, in the countryside, with only an officiant (and Seyfried's beloved dog Finn) present. It set the template for everything that followed: major life events handled privately, on the farm, away from the industry's gaze. Nine years later, Nina is growing up in the same Catskills world she was born into.

Thomas Sadoski Jr. (Age 6)

Thomas Sadoski Jr. was born in September 2020, on the family's farm in upstate New York. He is 6 years old as of October 2026.

His arrival was a genuine surprise to the public: Seyfried kept the entire second pregnancy under wraps, and the birth announcement came as news to fans. The couple has never publicly disclosed extensive details about him — consistent with their approach of fiercely protecting their children's privacy and rarely showing their faces on social media.

Thomas Jr. completed the family of four. Named after his father, he is the younger sibling in a household that, by every public account, revolved around farm life, animals, and creative work rather than celebrity machinery.

Keeping an entire pregnancy private in 2020 — the year of peak social media documentation — was itself a statement. Seyfried simply did not announce it, and Thomas Jr.'s arrival that September was news precisely because no one had been told to expect it. The couple has never publicly disclosed extensive details about their son, and the few glimpses Seyfried shares keep his face and daily life out of frame.

The Separation: What Was Actually Said

Because this story is still unfolding, precision matters more than speed. Here is what is confirmed: on September 15, 2026, Seyfried (40) and Sadoski (50) gave PEOPLE an exclusive joint statement confirming they had separated after nine years of marriage. The statement said they had 'been separated for a while' and that the decision had 'proven to be the right move for us and our family unit,' closing with: 'We've got each other forever — and it's GOOD.'

What was not said: no reason for the separation, no timeline of when it began, and no mention of divorce filings. The pair emphasized an ongoing mutual bond and dedication to their family — they share two children, Nina (9) and Thomas Jr. (6) — and presented the decision as considered rather than sudden.

The public dynamic since has stayed warm: hours before the news broke, Seyfried shared a casual photo of Sadoski on her social media, and Sadoski has continued supporting her work publicly. Earlier in 2026, Seyfried had praised Sadoski for 'sacrificing a lot' at home while she worked. As of October 2026, the through-line is co-parenting continuity — two parents, separated, jointly raising two kids on the terms they set together.

Farm Life: Raising Kids Away From Hollywood

To understand Nina (9) and Thomas Jr. (6), you have to understand the farm. Seyfried bought her property in upstate New York's Catskill Mountains in 2013 — years before marriage and children — and it has been the family's center of gravity ever since. The kids are growing up around animals, land, and weather rather than premieres and paparazzi, and Seyfried has described the arrangement as deliberate insulation: 'It's way less Hollywood noise,' she told Net-a-Porter. '[My children] know that I'm a recognized person in the world, that I'm an actor and that me being on TV is very normal for them. And they also know that they're safe at home and have their own privacy — and that's everything.'

The farm is also a working part of Seyfried's identity — she is known for her hands-on involvement with the property and its animals, a contrast with the glamour of her screen career that she seems to relish. During the marriage, Sadoski was a visible part of that life too, and the couple's joint philanthropic work (including support for War Child USA) suggested shared values beyond the farm gates.

What the September 2026 separation changes about this picture is, as of October 2026, unconfirmed — and this guide will not speculate. What is confirmed is the foundation: two children raised with unusual normalcy, two parents committed to co-parenting, and a family unit the couple themselves described as intact even as the marriage ended. 'We've got each other forever — and it's GOOD.' For Nina and Thomas Jr., that is the sentence that matters.

The timing is worth noting for context. The separation announcement came during one of the busiest professional stretches of Seyfried's career — with The Housemaid in theaters, The Testament of Ann Lee earning awards-season attention, and the Netflix film Steps slated for November 2026 — while Sadoski prepared for the Broadway production Downstate opening in October 2026. That both parents maintained a warm, united public front through it, with Seyfried praising Sadoski's sacrifices at home as recently as January 2026, suggests the co-parenting arrangement was built on a functioning partnership, not a broken one. As of October 2026, Nina is 9, Thomas Jr. is 6, and the farm remains home.
