Mandy Moore Is 'Totally Ready' to Have Kids After Playing a Mom on 'This Is Us'

The 32-year-old actress plays both a mom and a grandmother on the beloved series.

Mandy Moore would like her real life to somewhat mirror her character Rebecca's life on This Is Us.

While on Conan O'Brien's late-night show on Wednesday, the 32-year-old actress revealed that portraying a mother of three on the hit NBC show has made her "totally ready to have kids."

Moore admitted that while shooting This Is Us, she found herself looking out for her onscreen kids, who are played by Mackenzie Hancsicsak, Parker Bates and Lonnie Chavis. "We have three extraordinary young actors on the show, who have fantastic parents by the way. They’re very attentive," she gushed. "I think it’s a lot of their first jobs for most of them and any time there’s a scene that requires them to eat, I have to remind them."

Moore added that Milo [Ventimiglia] also gets paternal with their young co-stars during the dinner scenes. "Milo, who’s my husband on the show, we’re always like, ‘Guys slow down because you guys don’t realize you’re committing yourself to eating that same amount for the entirety of the scene which can sometimes be a couple hours.'"

Moore also recalled, "I remember we were shooting the Christmas episode and there was some melted peppermints in a candy dish that wasn’t even from the prop department. Clearly, it was set decoration and I turn my back for one second ...and all of them have jammed peppermints in their mouths!"

While the Walk to Remember actress has been very vocal about wanting kids of her own, she confessed that she didn't have much experience with children before the show. "I mean, we get to hold these newborn children, and I can’t believe their parents were willing to hand over their babies to me," she quipped. "I’m like, ‘Hi, I’m Mandy. I have absolutely no experience with small children,' and they’re like, ‘Here’s my 2-week-old baby.’”

Moore said the cast and crew have been great about giving her parenting tips. "I didn’t know how to change a diaper,” she shared. "I had crew members showing me how to change a diaper. I’m terrible, but yes it has sort of activated that maternal side of me that I’m totally ready to have kids now.”

In an exclusive interview with ET, Moore also praised Ventimiglia for being a great onscreen husband and father. "He's such a special guy, it's really not hard to have to just love him," she said of her handsome co-star. "I feel very safe. I feel very, like, protected with him."

"I've never really felt that with somebody I've worked with before, so I feel incredibly lucky every day just to have this job, but then to get to work with him every day, too," Moore added. "I know I'm in good hands."
