Elizabeth Olsen has officially become a mother.

The 37-year-old actress, best known for playing Wanda Maximoff in the Marvel Cinematic Universe and the acclaimed Disney+ series WandaVision, has welcomed her first child with husband Robbie Arnett, 34.

The couple, who have long maintained a relatively private relationship, have not publicly announced the baby’s name, sex or exact date of birth. However, new photographs taken in Los Angeles appear to confirm that Olsen has recently given birth.

According to photos obtained by Page Six, Olsen was seen in Los Angeles on Saturday, August 15, carrying a newborn in a white baby carrier strapped to the front of her body.

The sighting marked the clearest confirmation yet that the actress and Arnett had quietly entered a new chapter of their lives together.

Representatives for Olsen did not immediately respond to PEOPLE’s request for comment.

Olsen Was Recently Spotted Without Her Baby Bump

The photographs followed another recent sighting of Olsen in Southern California.

Earlier in August, the actress was reportedly photographed without the visible baby bump she had been seen with just weeks earlier, prompting speculation that she had already welcomed her first child.

That speculation was strengthened by the August 15 images showing Olsen carrying the infant.

The actress has not made a public statement about becoming a mother, consistent with the understated way she and Arnett have handled many major moments in their relationship.

Their pregnancy had similarly remained out of the spotlight for much of the time.

It was only publicly confirmed in June 2026, when Olsen was photographed during a lunch outing at a restaurant in Los Angeles.

During that appearance, the actress wore a loose white button-down shirt. The bottom of the shirt was left open, revealing her baby bump.

Photographs also showed Olsen placing a hand on her stomach.

The images confirmed that she and Arnett were expecting their first child, although neither of them subsequently shared extensive details about the pregnancy.

A Relationship Built Away From the Spotlight

Olsen and Arnett have been together for nearly a decade.

Arnett is a musician and a member of the indie-pop band Milo Greene. The couple began dating several years before making their relationship more permanent.

In July 2019, a source confirmed to PEOPLE that Olsen and Arnett had become engaged after approximately three years together.

However, just as they would later keep much of Olsen’s pregnancy private, the couple avoided a highly publicized wedding.

They quietly eloped sometime before the COVID-19 pandemic began in 2020.

Olsen later explained that the couple eventually held another wedding celebration, but their legal marriage had already taken place before the pandemic dramatically disrupted travel and large gatherings around the world.

Their decision to marry privately reflected a pattern that has defined much of their relationship.

Unlike many Hollywood couples who regularly share intimate milestones online, Olsen and Arnett have generally kept details of their life together away from social media and public attention.

Elizabeth Olsen Prefers Quiet Nights at Home

Olsen has occasionally offered glimpses into what her marriage looks like behind the scenes.

At the November 2025 premiere of her film Eternity, the actress spoke with PEOPLE about her relationship with Arnett and explained that both of them tend to be more introverted than extroverted.

Rather than seeking elaborate nights out, Olsen said the couple usually enjoys spending time together at home.

When asked about her ideal date while living somewhere active and busy such as Los Angeles, Olsen described something noticeably simple.

Her “dream date,” she said, would involve cooking a meal at home and watching a movie.

The comment offered a small window into the private domestic life that Olsen and Arnett have carefully maintained despite her international fame.

That preference for privacy also helps explain why the couple has so far shared little information about their newborn.

A New Chapter for the WandaVision Star

Motherhood marks another major milestone for Olsen, whose career has evolved significantly since she first emerged as an actress in the early 2010s.

Although she comes from one of Hollywood’s most recognizable families as the younger sister of Mary-Kate and Ashley Olsen, Elizabeth built a distinct acting career through independent films before becoming part of one of the entertainment industry’s biggest franchises.

Her breakout work included performances in films such as Martha Marcy May Marlene, which helped establish her reputation as a dramatic actress.

Her career reached a much wider international audience after she joined the Marvel Cinematic Universe as Wanda Maximoff, also known as the Scarlet Witch.

Olsen first appeared briefly as the character in the Marvel universe before taking on a major role in Avengers: Age of Ultron.

She subsequently returned in several Marvel productions, including Captain America: Civil War, Avengers: Infinity War and Avengers: Endgame.

However, it was the 2021 Disney+ series WandaVision that gave Olsen one of the most prominent roles of her career.

The series placed Wanda at the center of an unusual story blending superhero action with classic television sitcom formats and a deeper exploration of grief, loss and emotional trauma.

Olsen’s performance received widespread recognition and further elevated her status as one of Marvel’s most prominent performers.

She later reprised the character in Doctor Strange in the Multiverse of Madness.

Outside Marvel, Olsen has continued balancing major studio productions with smaller dramatic projects.

Her more recent films have included His Three Daughters and Eternity, allowing her to continue exploring roles outside the superhero genre.

Olsen and Arnett Have Also Worked Together Creatively

Olsen and Arnett’s partnership has extended beyond their personal relationship.

The pair collaborated on the children’s book Hattie Harmony: Worry Detective, demonstrating a shared interest in creative projects outside their primary careers.

The book focuses on helping children understand and manage anxiety, with its central character assisting classmates who encounter stressful situations.

Their collaboration offered another example of how the couple has built a life that blends their artistic interests while remaining relatively removed from celebrity culture.

Now, the arrival of their first child introduces an entirely new dimension to their relationship.

Although Olsen has spent much of her adult life working on film sets, attending premieres and promoting major productions around the world, she has repeatedly suggested that her personal priorities are considerably quieter.

Her comments about enjoying home-cooked dinners and movies with Arnett appear particularly fitting as they begin life as parents.

The Couple Remains Private About Their Baby

For now, Olsen and Arnett have chosen not to publicly reveal further details surrounding their child’s birth.

The newborn’s name, sex and exact birthday have not been announced, and there has been no indication that the couple plans to make those details public immediately.

The approach is consistent with how they handled Olsen’s pregnancy.

Rather than announcing the news through a major social media post or magazine feature, the pregnancy became publicly known after Olsen was photographed in Los Angeles in June.

Similarly, confirmation that the baby had apparently arrived came through photographs of Olsen carrying the infant rather than a formal announcement from the couple.

For two people who have repeatedly demonstrated a preference for keeping important moments private, the quiet arrival appears entirely consistent with the relationship they have built.

After years together, an engagement in 2019 and a private marriage before the pandemic, Elizabeth Olsen and Robbie Arnett are now beginning their next chapter as parents to their first child.
