The baby on the way will be Neisen's first child. Schreiber, whom she first started dating in 2017, shares two children — Kai, 14, and Sasha, 16 — with ex Naomi Watts.

The former Miss South Dakota and Schreiber, who tend to stay out of the spotlight for the most part, appear to get along well with Schreiber's ex, who referred to the crew as a "modern family" in a June Instagram photo that also included Watts' husband, Billy Crudup.

"Congratulations to Kai ⚡️🎉Class of 2022 #modernfamily ❤️ #graduation," Watts captioned the happy moment.

Keeping his message simple with a "Congratulations!!!!" Schreiber posted a photo of Watts posing with Kai as the two held flowers. He also shared a sweet photo of Kai holding up their graduation certificate.

Despite Schreiber's star status, the actor admitted to Ellen Degeneres in 2019 that his then-preteen kids didn't consider him "cool."

“You’re never cool to your own kids,” Schreiber said. “I don’t know anybody who is cool to their own kids.”

The Tony Award-winning actor revealed he even took on roles in animated movies such as Isle of Dogs, hoping to impress his children.

“And my kids, their reaction to them is, ‘Yeah, but you’re just a voice.’ And I’m like, ‘Yeah, but I’m one of the main characters!’ And they’re like, ‘Yeah, but you’re the bad guy.’ "

“It’s like ... I’ve just accepted the fact that it’s impossible,” Schreiber added. “I’ll never be cool.”
