Jon Hamm and his wife, Anna Osceola, are expecting their first child, according to a source who confirmed the news on Monday.

The couple, who wed in Big Sur, California, in June 2023, have been together since 2020. Hamm, 55, and Osceola, 38, first met in 2015 on the set of "Mad Men," but did not begin dating until five years later. Hamm proposed in February 2023.

In a June 2023 interview, when asked about starting a family, Hamm responded with "TBD," but noted he was in an "exciting part of life" characterized by "stability and comfort."
