Jon Hamm Reveals He and Anna Osceola Are Expecting Their First Child

Jon Hamm has revealed that he and his wife Anna Osceola are expecting their first child together — dropping the happy news during a candid appearance on Late Night With Seth Meyers that also touched on an unplanned comedy moment at the Emmys and his new MGM+ drama series.

The actor made the announcement during a wide-ranging conversation with host Seth Meyers, sharing that he and Osceola are set to become parents for the first time. The news was warmly received by the studio audience, and Hamm — long known for his composed, understated public persona — appeared visibly delighted as he discussed the milestone.

The couple, who married in 2023, have kept their personal life relatively private, making the Late Night reveal all the more welcome for fans who have followed Hamm's career from his Mad Men days through to his current renaissance as one of television's most in-demand leading men.

The baby news wasn't the only talking point from the appearance. Hamm also entertained Meyers and the audience with a candid account of an unscripted moment during his recent stint presenting at the Emmy Awards, where he reportedly ad-libbed a joke in High Valyrian — the constructed language from Game of Thrones — to considerable effect.

It was precisely the sort of self-aware, lightly eccentric moment that Hamm has become known for in his television appearances — effortlessly charming while gently poking fun at the absurdity of Hollywood ceremony.

The personal news arrives as Hamm launches what is shaping up to be one of the more compelling new series of the autumn television season. American Hostage, now streaming on MGM+, is a true-crime thriller set in 1977 Indianapolis, in which Hamm plays Fred Heckman — described in the show as 'the most trusted voice in news' — a veteran radio journalist thrust into the centre of a volatile hostage situation.

The eight-episode series is based on the first season of the American Hostage podcast from Criminal Content, and was created by Shawn Ryan and Eileen Myers, the team behind The Night Agent. Giovanni Ribisi co-stars as Tony Kiritsis, a former used car salesman who has taken a mortgage executive hostage at gunpoint, demanding Heckman interview him live on air. Mireille Enos, William Jackson Harper, and Kristoffer Polaha round out the principal cast.

Critical reception has been cautiously positive. The Hollywood Reporter described Hamm as 'likably understated' in the role, and praised Ribisi's performance as 'convincingly overstated,' though the review noted that the series 'starts off promisingly, peaks in the middle and overstays its welcome' across its eight-episode run. The show has been positioned as the first instalment of a planned anthology series, with future seasons set to explore different real-life hostage crises from American history.

The 1977 setting allows the series to mine themes of institutional distrust and media power that the creators clearly intend to resonate with contemporary audiences — drawing comparisons to Sidney Lumet's Dog Day Afternoon in its portrait of a man whose grievances, however explosively expressed, tap into something universally recognisable.

Between a new baby on the way, a buzzy new series drawing critical attention, and a memorable Emmys moment doing the rounds online, it is fair to say that autumn 2026 is shaping up rather well for Hamm. He also discussed his work on the American Hostage podcast series during the Late Night interview, giving Meyers insight into how he approached returning to a project he had previously worked on.

The Late Night segment also revisited an old clip featuring Paul Rudd, who had previously used the same chat show to retell an anecdote about a time he and Hamm were both competing for the same woman's attention — a story that has resurfaced on the programme's YouTube channel, to the evident delight of fans of both men.
