Elizabeth Olsen, Husband Robbie Arnett Expecting First Child

Elizabeth Olsen is expecting her first baby with her musician husband Robbie Arnett.

The "WandaVision" star, 37, was spotted out to lunch in Los Angeles at All Time Restaurant this week, wearing a white button-down shirt that was left open at the bottom to reveal her baby bump.

The soon-to-be first-time mom was photographed holding her stomach.

Olsen and Arnett quietly eloped sometime before the coronavirus pandemic in 2020.

The actress has been pretty private about her relationship with Arnett ever since the pair were first spotted together in March 2017.

Nearly two years later, Olsen and Arnett got engaged in July 2019.

At the time, a source confirmed that the engagement followed three years of dating.

In June 2021, Olsen surprised fans when she called Arnett her "husband" during an interview with Variety.

During the video chat with Kaley Cuoco, which was released as a part of Variety's Actors on Actors series, Olsen pointed out that Arnett had left a particular book in the room.

"I also just noticed that my husband put Little Miss Magic," Olsen explained, gesturing to a book from the "Little Miss" book series, which could be seen in the background.

This past November, Olsen spoke with PEOPLE and shared that she and her husband tend to lean more introverted than extroverted.

“Depends what city I'm in,” the actress-producer said when asked about favorite date night activities. “We're in L.A., so I guess my dream date there is cooking a meal at home and watching a movie.”

As for whether her husband Arnett prefers nights in? “Oh, yeah, definitely,” Olsen told PEOPLE with a laugh. “I had to drag him here.”
