Fox shares sons Noah, 12, Bodhi, 10, and Journey, 8, with her ex-husband Green, 51, whom she split from in 2020 after a 16-year on-and-off relationship. They tied the knot in 2010.

Green is also a father to Kassius Lijah, 22, whom he shares with ex Vanessa Marcil, 56, as well as son Zane, 2, with Burgess. Meanwhile, Kelly (real name Colson Baker) is a dad to daughter Casie, 15, whom he shares with his ex Emma Cannon.

While making her baby announcement on Monday, Fox referenced her and Kelly's past pregnancy loss. "Nothing is ever really lost. welcome back 👼🏼❤️," she captioned the Instagram post.

Fox and Kelly — who announced their engagement in January 2022 — first met on the set of Midnight in the Switchgrass in March 2020. The two went public with their relationship after Fox appeared in Kelly's "Bloody Valentine" music video in May 2020. The video came just days after Green confirmed their split after almost 10 years of marriage.

The Jennifer's Body actress previously hinted at the idea of having a baby with Kelly when she and Kourtney Kardashian introduced the rocker and Kardashian's husband Travis Barker at the MTV Video Music Awards in 2021.

"New York, I need you to get extra loud for our future baby daddies," Fox told the crowd.

She then opened up about experiencing a miscarriage in November 2023, via two poems featured in her book Pretty Boys Are Poisonous.

"I’ve never been through anything like that in my life. I have three kids, so it was very difficult for both of us and it sent us on a very wild journey together and separately… trying to navigate, ‘What does this mean?’ and ‘Why did this happen?’ ” Fox told Good Morning America of the pregnancy loss at the time of the book's release.
