Milo Ventimiglia says the one thing he misses the most about 'This Is Us' is working with Mandy Moore

• Milo Ventimiglia revealed that what he misses most about filming "This Is Us" is Mandy Moore.
• He told InStyle he's exchanged messages with her recently to check in on her family.

In a new interview with InStyle, Milo Ventimiglia revealed that what he misses most about "This Is Us" is working with his former on-screen wife.

"Mandy Moore," he replied to reporter Jenna Brillhart when asked what he misses most about playing the Pearson family patriarch. "I miss my friend."

The actors were living on different coasts for a while as Ventimiglia filmed "The Company You Keep" in Los Angeles and Moore shot one of her upcoming projects in New York.

"We've recently sent some messages back and forth," Ventimiglia continued. "I was checking in on her and her husband, and the babies, and whatnot, and she [was] checking in on life over here."

Moore gave birth to her son Oscar Bennett in October 2022. She and her husband, musician Taylor Goldsmith, are also parents to August "Gus" Harrison, 2.

Their real-life relationship is purely platonic, but the world fell in love with Ventimiglia and Moore as spouses Jack and Rebecca Pearson. As Ventimiglia revealed to Jimmy Fallon in January 2022, when the cameras were rolling, they took their fake marriage very seriously and even made real vows about their commitment to each other.

He recalled to Fallon that early on while promoting "This Is Us" at NBC upfronts, the pair "almost took vows with one another."

The "Gilmore Girls" actor went on to recite some of those promises: "I promise to always communicate. I promise to not be happy until you're happy. I will always look out for you."

"And we have stayed very true to what we said in the beginning," Ventimiglia explained, calling Moore "the best partner I've ever had."

Moore has echoed Ventimiglia's sentiments in the past. She once told Popsugar that Ventimiglia asked to nuzzle "into my neck and pretended to be my husband."

"I was like, 'Oh, wow, this is how it's supposed to feel.' It was great," she recalled.

Ventimiglia's new show "The Company You Keep" airs Sunday at 10 p.m. ET on ABC.
