Elizabeth Olsen is preparing to welcome her first child with her husband, Robbie Arnett.

The 37-year-old Marvel actress, who is the younger sister of Mary-Kate and Ashley Olsen, is pregnant, according to a report confirmed by People on Friday.

Olsen appeared to quietly reveal her growing baby bump during a lunch outing at All Time restaurant in Los Angeles.

As she exited the restaurant, the actress was seen softly resting a hand on her stomach.

She and Arnett have largely kept their romance private since they started dating in 2017.

Reports say the pair met through mutual friends while on vacation in Mexico. They made their public debut later that year, moved in together in 2018, and sparked engagement speculation 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.

‘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 was 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.

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

But life with the twins was not 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.’

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