Kate Mara shared some fantastic news with fans on Instagram on Sunday. The actress is expecting another baby!

Kate shared a picture of herself and her husband Jamie Bell holding hands while leaving this year's BFI Chairman's Dinner in London on June 28th. She captioned the photo: "There are three of us in this pic."

The pair met while filming the third "Fantastic Four" film in 2015 and eventually married in July 2017. They share a daughter, who's name has not been shared with the public since her birth in 2019. After giving birth, the "Martian" actress shared a photo of her daughter's feet and captioned the post:

We had a baby a couple weeks ago...Here are her feet."

In addition to a baby girl, Jamie is father to an 8-year-old son, Jack, who Bell had with his ex Evan Rachel Wood. Mara opened up about being a stepmom in an interview with "US Weekly." She said:

“I come from a really, really big family, and I’ve had kids around me my entire life. Family is everything to me, and I like being surrounded by lots of kids and family at all times."
