Elizabeth Olsen is pregnant as Marvel star expecting first baby with husband Robbie Arnett

Marvel star Elizabeth Olsen is expecting her first child with husband Robbie Arnett.

The 37-year-old actress - younger sister of twins Mary-Kate and Ashley Olsen - is pregnant, with People confirming the news on Friday.

Olsen appeared to subtly showcase her baby bump during a lunch outing in Los Angeles at All Time Restaurant.

The actress was photographed gently cradling her stomach as she left the venue, sparking further attention around the news.

Olsen has kept her relationship with Arnett largely out of the spotlight since the couple first began dating in 2017. 

The pair reportedly met through mutual friends while vacationing in Mexico, made their first public appearance the same year and moved in together in 2018, with engagement rumors circulating in 2019.

Two years later, Olsen fueled further speculation when she referred to the Milo Green musician as her 'husband' during a Variety interview.  

Olsen then confirmed in 2022 that she and Arnett had quietly married prior to the coronavirus pandemic, revealing the news in a candid interview.

‘We eloped and then we had a wedding at another time,’ Olsen divulged to Jess Cagle Show listeners. ‘It was before COVID.’

Even before that, the actress had openly reflected on starting a family while balancing her demanding career. 

During a 2021 SiriusXM interview, she mused about timing motherhood around her professional commitments.

‘At what point do I get pregnant? At what point do I have my first baby?’ she asked. ‘Is that five years from now? Because then I only have this kind of a window.’

Before dating Arnett, Olsen was engaged to her Very Good Girls co-star Boyd Holbrook, with the pair ending their relationship in 2014 after three years together. 

The pregnancy news comes nearly six months after Olsen got candid about growing up in the shadow of her famous twin sisters - and the chaotic family life that shaped her.

The twins became household names as toddlers, sharing the role of Michelle Tanner on Full House, and went on to build an onscreen empire - all before they even turned 16. 

Now 39, they’re better known for their fashion empire than their TV roots.

Elizabeth had to fight for her own spotlight, eventually rising to stardom as a Marvel actress. 

But life with the twins wasn't always easy during what she calls a 'chaotic childhood', during her interview with The Times. 

She revealed: 'They were forced to watch all my plays my whole life and go to my dance performances.'

Did the twins ever give her advice? 

'No. We’re just a supportive family. It feels irrelevant to talk about it after 15 years of working,' the Eternity star said. 

'I was the youngest of four. We were all born within five years.'

Elizabeth is the daughter of exes Jarnette and David Olsen, who share her brother James Trent and the twins Mary-Kate and Ashley.
