Olivia Millar is a fashion entrepreneur and business owner who has recently gained public attention through her relationship with actor and director Jonah Hill. Professionally, she is the co-founder of Chasseresse, an online vintage clothing store she operates with her sister, Raychel Millar. The brand focuses on curated, sustainable, and regenerative fashion, drawing on Millar’s background in the industry.

She comes from a notable fashion lineage as the daughter of Esmé Marshall, a prominent top model in the 1980s. Despite her family’s history in the limelight, Millar is known for being intensely private. She maintains a low profile, keeps her social media accounts private, and generally avoids public events and media scrutiny.

In early 2026, her personal life became a topic of public interest after Jonah Hill confirmed during an interview with Martin Scorsese that the two are married. The couple was first linked in late 2022 and welcomed their first child in May 2023. More recently, in April 2026, it was revealed that they have quietly welcomed their second child together.

Early Life and Roots: A Heritage of Style

To understand the Olivia Millar biography, one must look at the foundation of her upbringing. Olivia was born into a family where style wasn’t just a choice—it was a legacy. Growing up in a household that appreciated art and expression, she developed a keen eye for detail and a deep-seated respect for the history of fashion.

Parents: The Legacy of Esmé Marshall

Olivia is the daughter of Esmé Marshall, a legendary top model who dominated the fashion industry in the 1980s. Marshall was a muse for some of the world’s most renowned photographers and was a frequent face on the covers of Vogue and Harper’s Bazaar. This lineage provided Olivia with an insider’s view of the industry from a very young age, though she notably chose to work behind the scenes rather than in front of the camera like her mother.

Siblings and Family Bond

Olivia shares a particularly close relationship with her sister, Raychel Roberts (also known as Raychel Millar). Unlike Olivia, who prefers the shadows of privacy, Raychel followed more closely in their mother’s footsteps as a model. However, the sisters found common ground in their shared love for vintage clothing, a bond that eventually led to their professional partnership.

Education and Academic Background

While Olivia Millar is notoriously private about the specific institutions she attended, her professional output suggests a highly refined education in design, business, and art history.

Refining the Aesthetic: Those close to her business ventures note that Olivia possesses a deep knowledge of textile history and garment construction.
Business Acumen: Her ability to launch and sustain a niche online brand like Chasseresse indicates a background or a natural talent for digital marketing and e-commerce logistics.

The Professional Journey: Career and Chasseresse

The most significant chapter of the Olivia Millar biography in terms of career is the 2018 launch of Chasseresse. Co-founded with her sister Raychel, the brand was born out of a desire to combat “fast fashion” and provide a platform for “regenerative” style.

The Vision Behind Chasseresse

Chasseresse is more than just a vintage shop; it is a curated experience. Olivia and Raychel spend countless hours sourcing rare pieces from across the globe, focusing on:

Sustainability: Promoting the reuse of high-quality garments to reduce environmental impact.
Curation: Selecting items that tell a story, often featuring designs from the 70s, 80s, and 90s that remain timeless.
Modern Utility: Styling vintage pieces in a way that feels contemporary and accessible for the modern woman.

Role as an Entrepreneur

As the co-owner, Olivia handles everything from the creative direction of photoshoots—where she occasionally models the clothes herself—to the logistical back-end of the online store. Her work has been featured in major publications like Vogue, cementing her status as a tastemaker in the sustainable luxury space.

Personal Life: The Mystery of Olivia Millar

In an era where most public figures share every meal on Instagram, Olivia Millar is a ghost. She maintains private social media accounts and rarely grants interviews. This “allure of the unknown” has only made her more fascinating to the public.

How She Met Jonah Hill

Olivia and Jonah Hill were first spotted together in September 2022 in Santa Barbara, California. While the exact details of their meeting remain a closely guarded secret, sources suggest they met through mutual friends within the creative circles of Los Angeles and New York.

Wedding and Marriage: A Secret Union

For years, fans speculated about their marital status. In early 2026, during a landmark interview with Martin Scorsese for Interview Magazine, Jonah Hill casually referred to Olivia as his “wife.” This confirmed what many had suspected: the couple had quietly tied the knot in a private ceremony, away from the prying eyes of the media.

Motherhood: Growing the Family

Family is the cornerstone of Olivia Millar’s current life. She and Jonah have quickly expanded their “nucleus,” as Jonah describes it.

First Child: The couple welcomed their first child in May 2023. While they have chosen not to reveal the child’s name or face to protect their privacy, Jonah has frequently spoken about how fatherhood has fundamentally changed his perspective on life and work.
Second Child: In April 2026, it was revealed that Olivia and Jonah had quietly welcomed their second child. Jonah noted in recent press that “only the editing room” can separate him from his family now, highlighting Olivia’s role in creating a grounded home life.

Conclusion

The Olivia Millar biography is a testament to the power of living intentionally. In a world that often demands overexposure, Olivia has chosen the path of a “quiet mogul.” She is a woman who honors her past—through her mother’s legacy and her vintage business—while building a future centered on family and sustainability.
