How old is Jon Hamm? The ‘old dad’ opens up about becoming a father at such an age with wife Anna Osceola

Jon Hamm, the “Your Friends & Neighbors” star, is about to take on a role he once seemed unsure he would ever have. The star has always been honest about the mixture of excitement and fear he feels at the prospect of becoming a father. Since his wife, Anna Osceola, is now expecting their first child, Jon Hamm has been speaking more openly about what this new phase means to him.

His remarks also cause a surprising aspect from his earlier life to come back into sharp focus. Having once admitted that he did not have a strong desire to have children, Hamm is now at the age of 55 preparing to become the so-called "old dad" jokingly.

How old is Jon Hamm?

Jon Hamm, who is 55, is now getting ready to become a father with his wife Anna Osceola, who is 38 years old. The news of their pregnancy first appeared in August, and Osceola later displayed her growing bump at the Emmys 2026 red carpet, as quoted in a report by Page Six.

During an appearance on “Late Night With Seth Meyers,” Hamm opened up about the emotions surrounding the pregnancy.

“I think I’m doing it right,” the actor said, describing himself as “very excited and deeply terrified.” He added that he does not think those feelings should ever “go away.”

Hamm also joked about becoming an older father, imagining a future in which his child reaches old age while he is still celebrating having made it through parenthood.

“When your kid is 70, you’ll be like, ‘I did it!’ When I’m 152.” The comments offered a glimpse into how Hamm is approaching a major change in his life.

How is Jon Hamm preparing for fatherhood?

Jon Hamm is 55 years old. He and Osceola married in June 2023 after being together since 2020. The couple first met five years earlier while working on “Mad Men” in Big Sur, California. They eventually returned to the same location for their wedding.

Hamm has previously described the ceremony as small and intimate. Speaking to “Jimmy Kimmel Live!” five months after the wedding, he said, “It was very sparsely attended, by our decision. It was small,” before calling the “perfect” wedding “great.”

His feelings about starting a family have also evolved over time.

In a 2012 Playboy interview, Hamm said, "I don’t have a driving force to have a baby. That said, I’m in a committed relationship, and if it ever came up, I’m not ruling it out.”

He also spoke then about his doubts surrounding marriage, saying, “I don’t mean to say that it shouldn’t mean things to other people. It’s just my experience. I don’t have that paragon of married life to look at and think, ‘Oh yeah, that’s it! That’s what I want!'”

What has Jon Hamm said about having children?

Jon Hamm later became more open to the possibility of starting a family. Speaking to The Hollywood Reporter the year after his marriage, he reflected on his childhood and his parents' divorce. He said he did not have a model of marriage that showed him how to find happiness, but meeting Osceola changed his outlook, as per a report by TODAY.

“Obviously, my parents were not married long,” said Hamm, whose mom died when he was 10, “so I don’t have a model to look at and go, ‘Oh, this is how one finds happiness.’ I just knew at a certain point I wanted to be with this person. But when I proposed, I was terrified. I was like, ‘What am I doing?’”

He also described their Big Sur wedding as an “emotional” experience that gave him “a reset, a reboot, a reframe, a reimagining.”

“So, it’s been great. And I hope it turns into kids. It’s not lost on me that I’m 53. I will be the old dad, but so it goes. It could be a good thing. We’ll see,” Hamm said.

Why is Jon Hamm excited about becoming a dad?

During his appearance on TODAY on Sept. 23, Hamm spoke again about the pregnancy while promoting his new series “American Hostage.”

“It’s great,” Hamm said. “The best thing I keep hearing is how much it changes you for the better. I’m very excited. I’ve been around kids my whole life. I’ve been a teacher, my nieces and nephews and all that stuff, so I’m excited to start our own family.

“And it’s thrilling. And terrifying.”

The TODAY anchors also surprised him with a special onesie referencing his love for Bravo programming and “The Real Housewives” franchise.

The outfit read, “Going to bed, so daddy can watch Bravo.” “Beautiful,” Hamm said. “This will get used, I can tell you that much.”

Hamm and Osceola have generally kept their relationship away from the spotlight, making his recent comments about fatherhood particularly notable. From once saying he had no strong drive to have a baby to now preparing for his first child at 55, Hamm's own words show how much his outlook on marriage and family has changed.
