Kate Mara and Jamie Bell are expecting their second child together and the actress revealed the news in a sweet Instagram post on Sunday.
The House of Cards star, 39, and Billy Elliott actor, 36, already share a daughter together after her birth in 2019. Jamie also shares a seven-year-old son with his ex-wife Evan Rachel Wood.
And now, Kate took to Instagram to reveal their family is set to expand.
Posting to the social media platform, she uploaded a shot of her and her hubby holdings hands as they walked down a street together.
Kate was wearing a pale pink dress with jewelled neckline and a leave jacket, while Jamie looked dapper in a smart suit and crisp white shirt.
She dropped in the news of her pregnancy by captioning the image: "There are three of us in this pic."
And her followers and famous pals were quick to send congratulatory messages to the stars.
American actress and star of Peep World was among those responding, simply saying: "Congratulations!!!"
Actor Michael B Jordan, who starred alongside the pair in the 2015 film Fantastic Four, was also on hand to message, adding three star emojis, while news personality Justin Sylvester wrote: "CONGRATS."
Actress Jenna Dewan also said: "Awwww congratulations loves!!!!"
Jamie and Kate tied the knot in 2017 before the pair welcomed their first daughter almost two years later.
They initially kept their daughter's birth - whose name hasn't been publicly revealed - a secret, waiting a number of weeks before sharing the news with their fans.
She later revealed she had experienced complications during her pregnancy after developing cholestasis during her third trimester.
According to Emmy Magazine in 2020, the star was induced and had to undergo an emergency C-section after three days of labour.
Prior to the birth of their daughter Kate suffered an early miscarriage.
She told prenatal-focused chiropractor Dr. Elliot Berlin's Informed Pregnancy podcast that she had had a first pregnancy that ended with a blighted ovum, a type of early miscarriage, shortly before falling pregnant again.
