Fantastic Four Star Kirby Welcomes First Child with Lacrosse Champ Rabil

On October 19, 2025, Fantastic Four actress Kirby, 37, and her partner Paul Rabil, 39, a former professional lacrosse player, welcomed their first child. Rabil took to Instagram to share the joyful news, posting photos of himself holding the newborn and Kirby with the baby in bed.

In the caption, Rabil expressed his gratitude for the family's health and Kirby's "enormous love," adding that they are excited to have the baby in their lives. He also included a photo of two miniature lacrosse sticks, joking that the baby's "first cradle stick" will "hold many stories and blessings" as well as "broken windows."

Kirby has not yet addressed the birth on social media, but the couple has been private about their relationship, which they made public in November 2023 after sparking romance rumors earlier that year. In April 2025, Kirby shared photos from a romantic getaway with Rabil, writing about appreciating the "people you most love."

The actress's pregnancy also played a role in her portrayal of the Marvel character Sue Storm/The Invisible Woman in the upcoming film The Fantastic Four: First Steps. Kirby has spoken about how her real-life experience of pregnancy influenced her understanding of the character, who is also a mother in the comics.
