Sienna Miller Husband: Is She Married to Oli Green?

Searches for Sienna Miller’s husband have grown as the British actress has settled into a quieter family life with actor and model Oli Green. The pair have been together for several years, share two children and are now engaged, so it is easy to understand why many people assume they have already married.

However, there is an important detail to clear up. Sienna Miller and Oli Green have not publicly confirmed that they are married. Green is currently known as Miller’s fiancé. Their engagement became public after Miller was photographed wearing a diamond ring, marking another major step in a relationship that has developed largely away from the intense tabloid attention Miller experienced earlier in her career.

For Miller, the relationship appears to represent a very different chapter. She is now a mother of three, she and Green have built a family together, and their romance has moved from relatively low-key beginnings to an engagement.

Is Sienna Miller Married?

Sienna Miller is not publicly confirmed to have a husband. Although she and Oli Green are engaged, no wedding between the couple has been announced publicly.

The confusion is understandable. Miller and Green live what looks from the outside like a settled family life. They have been romantically linked since 2022, have welcomed two children together and frequently attend public events as a couple. Their engagement was confirmed in June 2026 after Miller was seen wearing what appeared to be an engagement ring.

Recent coverage continues to refer to Green as Miller’s fiancé rather than her husband, meaning reports of the pair already being married should be treated carefully unless either of them confirms a wedding.

Miller has previously been engaged, most famously to actor Jude Law, but that relationship did not result in marriage. Her current engagement to Green is therefore another important personal milestone, but it should not yet be described as a confirmed marriage.

Who Is Oli Green?

Oli Green is a British actor and model who has gradually built his own career in entertainment and fashion.

Green studied acting at the Strasberg Theatre & Film Institute in New York before moving into professional screen work. His acting credits have included appearances in projects such as The Bold and the Beautiful, The Mosquito Coast, A Good Person and The Crown.

His work has not been limited to acting. Green has also developed a notable modeling career, appearing in campaigns for major fashion names. He has worked with Burberry and was featured in Gap’s “I Am” campaign. His modeling background places him in a world that naturally overlaps with Miller’s long relationship with fashion.

One particularly personal collaboration came when Miller and Green appeared together in a Frame denim campaign. The project was significant because it brought their real-life relationship into a professional fashion setting rather than simply presenting them together on a red carpet.

Green has therefore developed an identity beyond being Sienna Miller’s partner. While his relationship with a globally recognized actress brought him wider public attention, he had already been working across fashion and acting.

How Sienna Miller and Oli Green Met

Miller and Green were first publicly linked in early 2022. Their romance gained attention after they were seen together around the BAFTA Film Awards period, and they later made their red carpet debut at the Vanity Fair Oscar Party in March that year.

From there, their relationship became more visible.

They appeared together at fashion events, charity gatherings and major sporting occasions, including Wimbledon and the French Open. Even as public appearances increased, the couple did not turn their relationship into a constant social media spectacle.

That more private approach is particularly interesting considering Miller’s history with celebrity culture. During her twenties, her romantic life often received more media coverage than her acting. Her relationship with Jude Law became one of the most heavily covered celebrity stories of the mid-2000s.

With Green, things have unfolded differently. There have certainly been photographs and interviews, but the relationship itself has generally remained less dramatic and more family focused.

Their 15-Year Age Difference

One of the most discussed parts of Sienna Miller and Oli Green’s relationship is their age gap.

Miller and Green are around 15 years apart in age. When their relationship first became public, that difference attracted plenty of commentary. Miller has since spoken openly about the subject rather than pretending the age gap does not exist.

She has explained that she did not deliberately set out to date a younger man. Instead, the relationship developed naturally and became serious relatively quickly. She has also spoken positively about Green’s maturity and how attitudes toward relationships can differ between generations.

The age difference may have attracted headlines in the beginning, but it seems to have become less central as the couple’s relationship progressed.

Their years together, growing family and eventual engagement have increasingly become the bigger part of their story.

Sienna Miller and Oli Green’s Children

Family has become one of the most important parts of Miller and Green’s relationship.

The couple welcomed their first child together, a daughter, around the beginning of 2024. Miller had previously revealed that she was expecting another daughter while discussing her pregnancy.

Later, Miller became pregnant again with Green’s second child. She revealed her pregnancy publicly while attending the Fashion Awards in London in late 2025.

By May 2026, Miller confirmed that the baby had arrived. Later reporting identified the child as a boy. This made Miller a mother of three children and gave Green two children with the actress.

The couple have chosen not to reveal every detail about their younger children. Their daughter’s name has remained private publicly, reflecting the fairly careful boundaries Miller has maintained around her family life.

Miller’s eldest child is daughter Marlowe, whom she shares with actor Tom Sturridge. Marlowe was born in July 2012.

Miller and Sturridge dated from 2011 until 2015 and continued raising their daughter after their romantic relationship ended. That means Miller and Green’s household is part of a wider blended family rather than the actress beginning motherhood again from scratch.

When Did Sienna Miller and Oli Green Get Engaged?

Engagement speculation intensified after Miller was seen wearing a large diamond ring during a public appearance in Spain.

Soon afterward, reports confirmed that Miller and Green were engaged. The news arrived shortly after the birth of their second child together, making it a particularly eventful period for the couple.

The engagement felt like a natural progression after several years together rather than a sudden celebrity announcement.

By that stage, Miller and Green had already been together for around four years. They had traveled together, attended major public events, worked together professionally and become parents twice.

What they have not done, at least publicly, is announce wedding plans in significant detail.

There has been no confirmed wedding ceremony announced, which is why calling Oli Green “Sienna Miller’s husband” remains premature. For now, fiancé is the accurate description.

Was Sienna Miller Ever Married to Jude Law?

Sienna Miller’s past relationship with Jude Law remains another reason people sometimes assume she has previously been married.

Miller and Law met while working on the film Alfie in 2003. Their romance quickly became serious, and the couple became engaged in 2004.

However, they never married.

Their relationship went through a highly publicized period of turmoil and they eventually separated. They later reunited for a period before ending their relationship again.

Years later, Miller has spoken about how overwhelming that period of her life was. She was a young actress becoming internationally famous at the same time that intense media coverage focused heavily on her personal relationships.

That experience appears quite different from the more controlled and private way Miller has approached family life in recent years.

Sienna Miller’s Relationship With Tom Sturridge

After her relationship with Law, Miller later had a serious romance with actor Tom Sturridge.

The pair were together from 2011 until 2015 and welcomed their daughter Marlowe in 2012. Although the romantic relationship ended, Sturridge remained an important part of Miller’s life as Marlowe’s father.

Miller’s relationship history therefore includes several significant long-term partnerships, but none resulted in a publicly confirmed marriage.

That background makes the frequent search phrase “Sienna Miller husband” slightly misleading. She has had famous partners and more than one engagement, but marriage has not been publicly confirmed.

Sienna Miller and Oli Green Keep Family Life Private

Privacy appears to have become increasingly important to Miller as she has grown older.

She has experienced an unusual level of intrusion throughout her career, particularly during her relationship with Jude Law. That history likely explains why many aspects of her current family life remain outside the spotlight.

Green occasionally joins Miller at premieres, fashion events and industry gatherings, but the couple do not reveal every part of their relationship publicly.

The names and personal details of their younger children have also largely been protected.

Even their engagement emerged through public sightings of Miller’s ring before being confirmed rather than through an elaborate announcement.

That approach has allowed the couple to remain visible without making every development in their home life part of celebrity entertainment.

Where Their Relationship Stands Now

Sienna Miller and Oli Green appear to be in one of the most settled periods of their relationship so far.

They have been together since 2022, share two children and became engaged after welcoming their second baby together. Miller also continues raising her older daughter Marlowe, giving the family three children in total.

Green continues working as an actor and model, while Miller remains active in film, television and fashion.

The important distinction is that engagement is not the same as marriage.

There is currently no public confirmation that Sienna Miller and Oli Green have held a wedding or become husband and wife. Until such an announcement comes from the couple or is confirmed through reliable reporting, Green is best described as Sienna Miller’s fiancé and long-term partner.

For fans searching for Sienna Miller’s husband, Oli Green is almost certainly the man they are looking for. He is her partner, the father of two of her children and her fiancé, but not yet a publicly confirmed husband.
