Julia Stiles and Preston J. Cook Welcome Second Baby: "Welcome to the World"

Julia Stiles is officially a mom of two! On Jan. 26, Stiles announced that she and her husband, Preston J. Cook, have welcomed a new baby into their family. Along with the news, the actor shared a glimpse at how their 4-year-old son, Strummer, is handling the fact that he's now a big brother. "Welcome to the world, Baby Arlo! ✨," Stiles captioned the Instagram post. "The newest addition to our family, reminding me how infinite love can be. 💖 Scroll Forward to see how my 4 year old [sic] is taking it . . . ." The first photo in Stiles's Instagram carousel is an adorable peek at her new baby's feet wrapped in a hospital blanket, and the second photo shows Strummer's impromptu artwork splashed across the family toilet.

Stiles and Cook first met on set in 2015 while filming "Go With Me" and were engaged that same year. The couple got married on the beach two years later in September 2017 while Stiles was pregnant with their first child — whom they soon welcomed on Oct. 20, 2017. Stiles announced her second pregnancy in November 2021 when she cradled her pregnant stomach on the red carpet while attending a screening of "The Humans" at New York City's Village East Cinema. Congratulations to Stiles and Cook's growing family!
