Amanda Seyfried and Thomas Sadoski had a slow-burn romance before it fizzled out.
The pair met in May 2015 while working together on the Off-Broadway play The Way We Get By. At the time, Seyfried was in a relationship with Justin Long. Sadoski, for his part, was married to Kimberly Hope. Seyfried and Sadoski’s connection was strictly platonic while they were in their respective relationships.
In October 2015, Sadoski split from Hope after eight years of marriage. Seyfried also ended her two-year relationship with Long that same year. The Mamma Mia! star and Sadoski reunited for the film The Last Word in early 2016, and Us confirmed that the pair were an item after the duo were spotted arriving together on set.
Seyfried and the Newsroom alum secretly tied the knot in March 2017 while the actress was nine months pregnant with their daughter, Nina, who arrived less than two weeks later. The pair announced the birth of their second baby, son Thomas Jr., in September 2020 in a statement via the organizations INARA and War Child.
Sadoski and Seyfried announced in September 2026 that they split after nine years of marriage.
