Elizabeth Olsen Gives Birth, Welcomes 1st Baby With Husband Robbie Arnett: Report

Elizabeth Olsen and her husband, Robbie Arnett, have reportedly welcomed their first baby.

Olsen, 37, was spotted carrying a newborn in a baby carrier strapped to her chest in Los Angeles on Saturday, August 15, in photos obtained by Page Six. She did not immediately confirm her child’s arrival. Us reached out to the actress’ rep for comment. People also reported the news.

News of Olsen’s pregnancy broke in June when People obtained photos of the Marvel star cradling her baby bump during a lunch outing in Los Angeles. At the time, her belly peeked out the bottom of her white button-down shirt, which she left open.

Olsen’s decision not to publicly announce her pregnancy was in keeping with her proclivity for privacy when it comes to her personal life as she rarely speaks publicly about her relationship with Arnett. The couple began dating in 2017 before getting engaged in 2019 and tying the knot in 2020.

“I didn’t know I’d even want to get married or have kids [before I met him],” she recalled during a December 2025 appearance on the “Dear Chelsea” podcast. “I was actually renovating a house when we first started dating. I realized six months in that we’ll probably move into this house together and wanted him to be a part of making choices, so it didn’t feel like my space [but rather] our space.”

She added, “After living with each other for a very short period of time, [I realized] he’s truly the most comfortable person to be around and the greatest support in my life.”

Olsen went on to gush about Arnett’s best qualities during her discussion with host Chelsea Handler.

“He’s so sweet and funny and clever and smart,” she said. “His goal every day is to make me laugh, which is also annoying when I’m mad at him. He does it very quickly and early in the morning. He’s great. He’s a sensitive, kind, very good at communication [type of man].”

Elsewhere in the interview, Olsen offered insight into Arnett’s proposal, recalling how he “freaked out” because he thought “he needed there to be a cheeseboard [and a] fire in order for it to feel romantic or something.”

Despite the little details that didn’t come together to Arnett’s liking, Olsen was charmed by his proposal.

“He tried to go down on one knee … but we were on this wood dock,” she remembered. “He goes down on his knee and he’s, like, ‘Ow, this really hurts,’ and gets back up. It was just the two of us, [and] there’s not a single photo. It was just so lovely. I loved it so much just because it was him.”

Prior to her pregnancy, Olsen explained why she wouldn’t want her and Arnett’s future children to pursue any Hollywood dreams until they were grown.

“Hard no. My sisters [Mary-Kate and Ashley Olsen] are unique so it’s not a reflection on them when I say no, I think it’s a reflection more on culture today,” she told The Times of London in 2023. “Being younger today is already so complicated. To amplify it by being a child actor and then amplify it by social media, I just think it’s a lot for a kid’s development.”
