Amanda Seyfried Husband: From Their Stage Meeting to Separation

Amanda Seyfried’s husband, actor Thomas Sadoski, became her partner after the two met through theater and later worked together on screen. They married in March 2017 and share two children, Nina and Thomas. However, their relationship has since changed: in September 2026, Seyfried and Sadoski announced that they had separated after nine years of marriage, explaining that they had already been apart for some time.

The update adds important context to Seyfried’s earlier comments about their partnership. In a January 2026 Vogue interview, she praised Sadoski’s support during a demanding period in her career, saying he had made considerable sacrifices as major opportunities came her way.

Those comments remain part of their relationship history, but they describe an earlier moment. Their story now includes both the marriage they built and their decision to separate, alongside their continuing connection as parents.

Who Is Thomas Sadoski and How Did He Meet Amanda Seyfried?

Thomas Sadoski is an American actor with a career spanning theater, television and film. Many viewers recognize him from The Newsroom and Life in Pieces, while his stage work includes a Tony Award nomination for Reasons to Be Pretty.

His professional background is significant because he had an established acting career before marrying Seyfried. Their relationship began through shared work, with both bringing experience and an understanding of the demands of performing.

They first met while starring in the off-Broadway play The Way We Get By in 2015. The production placed them opposite each other as strangers navigating the aftermath of a one-night encounter following a wedding.

For Seyfried, the play was an opportunity to work in a different setting from the film roles that had made her widely recognizable. For both actors, it required the close collaboration that comes with rehearsing and performing a two-person relationship on stage.

Their initial meeting did not immediately become a public romance. Sadoski was married to Kimberly Hope at the time, while Seyfried had been in a relationship with actor Justin Long.

Sadoski and Hope divorced in 2015. Seyfried and Sadoski later began dating in early 2016, with their engagement confirmed that September.

Keeping those stages separate matters when describing their history. Meeting professionally in 2015, beginning a relationship in 2016 and marrying in 2017 were distinct developments rather than one continuous public announcement.

The pair also worked together in The Last Word, the film starring Shirley MacLaine that was released in 2017. Seyfried and Sadoski played romantic interests, adding a screen collaboration to their earlier theatrical connection.

The film is sometimes incorrectly described as a 2015 release. Its place in their story is clearer when it is identified as a 2017 movie, following the stage production where they first met.

Their relationship developed through a shared profession, but Sadoski’s career was never simply an extension of Seyfried’s. Both were working actors, familiar with the uncertainty, travel and scheduling pressures that accompany the job.

They married on March 12, 2017, choosing a private ceremony rather than a large public celebration. Sadoski subsequently revealed the news during an appearance on The Late Late Show with James Corden.

The timing made that month especially significant. Shortly after the wedding, the couple welcomed their first child, daughter Nina, bringing marriage and parenthood into the same period of their lives.

Their professional paths continued to overlap after the wedding. Both appeared in the 2023 limited series The Crowded Room, another project connecting their working lives several years after their first collaboration.

They also attended events together, including the 2022 TIME100 Gala and the opening night of the Broadway production Take Me Out that April. Such appearances became part of the public record of their marriage without revealing every detail of their life away from work.

Sadoski’s own projects continued across film and television. His credits around the period discussed in Seyfried’s January interview included American Sports Story, Lilly and Adult Children.

That background gives her comments about his support a practical context. She was describing a household in which two adults understood acting as a profession, while also making decisions about children, travel and the opportunities available to them.

Their Children, Career Support and September 2026 Separation

Seyfried and Sadoski share daughter Nina, born in March 2017, and son Thomas, welcomed in 2020. Parenthood became a central part of their family story while both continued working.

For much of their marriage, their home life was associated with a farm in upstate New York. The rural setting offered a different environment from the premieres, interviews and production schedules connected with their careers.

That contrast was visible in the January 2026 Vogue profile. Alongside discussion of Seyfried’s increasingly varied roles, the interview described someone whose life remained closely connected to family and familiar surroundings.

At the time, Seyfried was discussing a busy period involving The Testament of Ann Lee, The Housemaid and Long Bright River. The projects required different kinds of performances, while together representing a substantial professional workload.

Her remarks about Sadoski acknowledged the family effort behind those opportunities. She said he sacrificed a great deal and understood that the work being offered to her was exceptional.

She also made clear that she did not accept every project. Her explanation that she frequently turned work down suggested that even a successful run of roles involved choices about what the household could accommodate.

Those comments were a personal acknowledgment of support, rather than a claim that balancing work and family had become easy. They described the decisions involved when a parent’s career enters an unusually active phase.

Seyfried’s January comments should be read as an account of that period in her life. They do not override the couple’s later announcement or establish exactly when their private circumstances changed.

Their children were also part of the experience surrounding The Testament of Ann Lee. During filming in Europe in summer 2024, family members accompanied the production, according to the account provided by director Mona Fastvold.

Fastvold described children spending time together while spouses took turns helping and organizing outings. It offered a concrete example of how family arrangements could become part of making a demanding project possible.

That detail is more informative than a broad statement that a partner was always supportive. It shows the practical side of production life, where childcare, travel and working hours need to fit together.

Then, in September 2026, Seyfried and Sadoski publicly confirmed their separation. In a joint statement, they said they had been separated for a while and described the decision as the right move for their family.

Their statement also expressed an enduring bond. The announcement established that the relationship had changed, but it did not provide a detailed explanation of the reasons behind the separation.

It would therefore be speculative to attribute the split to her workload, a particular film or his professional choices. Earlier praise and a later separation can both belong to the same relationship history without proving a simple cause-and-effect story.

Separation also should not automatically be described as a finalized divorce. The public announcement confirmed that they were apart; any further legal development requires its own confirmation.

For readers asking about Amanda Seyfried’s husband, Thomas Sadoski remains the actor at the center of that history and the father of her two children. Their story includes a 2015 stage meeting, a 2017 wedding, shared parenting and years of professional encouragement. The latest confirmed chapter is their September 2026 separation, which gives a different context to the affectionate comments she shared earlier in the year.
