Julia Garner has separated from Mark Foster after more than six years of marriage. The split lands after a relationship that began in 2013, resumed years later on Instagram, and ended up in a December 2019 wedding that had a clear family echo.
Sundance Film Festival to City Hall
Garner and Foster first crossed paths at the 2013 Sundance Film Festival, then began dating five years later after reconnecting on Instagram. In early 2019, Foster asked her to marry him while reading a poem during a trip to Yellowstone National Park, and Garner later wore a diamond ring at the Dirty John FYC panel in Los Angeles.
The couple married at New York City Hall in December 2019. They wanted to honor the tradition of Garner's parents, who wed there 40 years earlier, and Foster wrote and performed the first-dance song, Lovers in a Stream, for the ceremony.
October and Fourth of July
The last public sighting of Garner and Foster came in October at the Hollywood 2025 after-party at the Chateau Marmont in Los Angeles. On the Fourth of July, Garner was spotted taking a walk without her wedding ring.
Garner and Foster also posted a black-and-white photo of themselves in the back of a car on 12/27/19, the day they married. That arc makes this breakup more than a tabloid beat: it marks the end of a public relationship that moved from a festival meeting to a city hall ceremony, then disappeared into private life before this latest turn.
Whether Garner or Foster will comment publicly on the separation has not been stated. For readers tracking the pair, the practical read is simple: the marriage is over, the timeline is now the story, and the next public signal will come from either of them, if it comes at all.
