AceShowbiz - Julia Stiles is now officially a mother of two. The actress has welcomed her second child with her husband Preston J. Cook and she couldn't help sharing the exciting news to her fans and followers Instagram.

Making use of her social media account on Wednesday, January 26, the 40-year-old revealed the arrival of her baby No. 2 along with the first glimpse of the newborn, whom she and her husband decided to name Arlo. The photo shows the baby's feet.

"Welcome to the world, Baby Arlo!" Julia wrote in the caption. She added, "The newest addition to our family, reminding me how infinite love can be." She has not revealed the baby's sex yet.

The "10 Things I Hate About You" actress also shared how her first child, 4-year-old Strummer Newcomb Cook, reacted to becoming an elder brother. She included a picture of her son's drawings with red marker on a toilet. "Scroll Forward to see how my 4 year old is taking it…," she informed her followers of the image in the second slide.

Julia and Preston, who met on the set of her 2015 movie "Go With Me", got engaged in 2016. In June 2017, she confirmed that they were expecting their first child. They got married in September of the same year and welcomed their son a month later in October.

The Golden Globe Award-nominated actress announced she's pregnant with her baby No. 2 in November 2021 when she debuted her baby bump on the red carpet of "The Humans" premiere at New York City's Village East Cinema.

Back in 2019, Julia discussed how becoming a mother has impacted her career. "One of the most remarkable things is that, in many ways, having my attention focused on my son has made me a better actress because I don't come home every night dwelling on every little scene, every little line, and obsessing over my work," she told PEOPLE. "It takes your focus off [the work], which makes you better [in the moment]."
