Kate Mara revealed she's pregnant with her second child with husband Jamie Bell on Sunday afternoon in a subtle, yet sweet Instagram post.
"There's three of us in this pic," the 39-year-old actress captioned a photograph of the couple from a night out in London.
Mara used an image from the BFI Chair's Dinner awarding BFI Fellowships to James Bond producers Barbara Broccoli and Michael G. Wilson at Claridge's on June 28, 2022, in London, England.
She tagged a Jamie Bell account which had 5,000 followers, no posts, and followed Bell's best friend, Max Minghella.

A slew of their Hollywood friends congratulated them on the understated announcement.
"Awwww congratulations loves!!!!," Jenna Dewan wrote, while Michael B. Jordan added a host of star emojis.
Octavia Spencer, Michael Pena, Andrew Rannells and Lara Worthington all sent warm wishes to the couple.

The couple first met on set of the Marvel Cinematic Universe flick, "Fantastic Four," in 2014, where she starred as Sue Storm/The Invisible Woman while he played The Thing.
Their relationship was kept mostly quiet until they were seen together at the MET Gala in 2015.

Mara, the great-granddaughter of the founders of both the New York Giants and the Pittsburgh Steelers, announced their engagement in January 2017 in a tweet showing off football gear from both of the teams.
Months later, the notoriously private couple married in Los Angeles. They each posted the same photo online to mark their July nuptials, and Bell went with the caption, "Me and Mrs. B."
Bell was briefly married to Evan Rachel Wood from 2012-14. They share an 8-year-old son, Jack Matfin Bell.
