If you’ve been wondering who exactly Olivia Millar is, you’re not alone. The internet lit up after Jonah Hill casually dropped a major personal update—he’s married, and he’s now a father of two. The kicker? He revealed it all in the most low-key way possible.
Here’s everything you need to know about Millar, their relationship, and the couple’s growing family.
Who Is Olivia Millar? A Look at Jonah Hill’s Partner
Olivia Millar isn’t a Hollywood regular, which is probably why so many people are curious about her. She’s known primarily as a fashion entrepreneur and co-owner of a vintage clothing brand, keeping a relatively low public profile despite her high-profile partner.
She also comes from a fashion-connected background—her mother, Esmé Marshall, was a model in the 1980s.
Millar and Hill were first publicly linked in 2022, and from the beginning, their relationship has been notably private. No red carpet overload, no constant social media posts—just occasional sightings and quiet milestones.

Here’s where things get interesting. For years, fans weren’t even sure if the two were engaged. But in April 2026, during promotions of his film “Outcome,” Hill confirmed something much bigger—he referred to Millar as his “wife” during an interview, effectively revealing they had secretly tied the knot.
There was no flashy announcement, no wedding photos—just a single word that changed everything.
That understated reveal perfectly matches how the couple has handled their relationship from the start: quietly, intentionally, and away from the spotlight.

The same interview came with another surprise—Jonah Hill shared that he and Olivia Millar have welcomed their second child.
“I have two kids now,” he said, while discussing how selective he has become with work projects.
The couple had already welcomed their first child in 2023, but just like everything else in their lives, details about both children—including names and genders—have been kept completely private.
Olivia Millar: A Relationship Built on Privacy
What makes Olivia Millar stand out in the celebrity ecosystem is how deliberately she and Hill have avoided the usual fame circus.
- They rarely make public appearances together
- They don’t share personal milestones online
- Even major life updates come out casually, not strategically
In an era of oversharing, their approach feels almost old-school—and it’s clearly working for them.
The Takeaway
At the center of all the buzz is Olivia Millar—a private figure who has quietly become a key part of Jonah Hill’s life.
From a low-key romance in 2022 to a secret marriage and now two kids, their story has unfolded almost entirely off-camera. And maybe that’s exactly the point.
Because while fans are just catching up, it seems like Millar and Hill have already built the life they wanted—just out of view.
