Hilary Duff and Mandy Moore’s friendship is what dreams are made of.
While occasionally crossing paths as teenagers in Hollywood, Duff and Moore became especially close after they welcomed babies in 2021.
“Hilary is a close friend, and she has a daughter who is six weeks younger than Gus,” the This Is Us alum said on a February 2022 episode of The Kelly Clarkson Show. “She’s, like, [a] super-mom — she has three kids — but she decided to start hosting this music class at her house.”
She continued, “It’s so much fun. I think in this time of COVID and having a kid in the midst of a pandemic, finding community to lean on, have your kids sort of start to grow up together. … I’m really grateful Hilary has done us all this giant favor.”
Duff shares son Luca with ex-husband Mike Comrie as well as three daughters with husband Matthew Koma. Koma is tight with Moore’s husband, Taylor Goldsmith. Moore and Goldsmith, for their part, are parents of three.

Duff and Moore both rose to fame in the early 2000s, even posing together for Vanity Fair’s now-infamous Young Hollywood issue alongside the Olsen twins and Lindsay Lohan.
“I remember being like, ‘This is cool I was included in this,’ but no, this was a very high stress, anxiety-inducing day,” Duff recalled to the outlet decades later in 2022. “Mandy and I are great friends now, so this is very funny.”

Duff organized a mommy-and-me music class for a group of celebrity moms including Moore, Meghan Trainor and Ashley Tisdale after they all welcomed babies earlier that year.
“Hilary is the coolest and she is a super-mom. She and Matt have become really close friends with my husband and I,” Moore told InStyle in 2022. “They have a kid who’s six weeks younger than [my son] Gus. And so, we had babies at the same time and she, being the super-mom that she is, formed a cool mom club.”
She continued, “Somehow, I got invited into it, and it’s the best. I’ve made so many wonderful friends. We all just gathered earlier this week and had dinner and we have baby classes together and it’s incredible. I’m very, very grateful to have those resources and just incredible women to be able to lean on. We’re all kind of going through this chapter of our lives together.”

After Moore and her husband lost their home in the devastating California wildfires, Duff and her spouse subsequently offered Moore’s family of five a place to stay.
“They are currently housing my brother’s family,” Taylor’s brother, Griffin Goldsmith, wrote via Instagram, noting Duff and Koma also set up a GoFundMe for his own brood after they lost their home too. “They’ve taken care of my entire family from the moment this began. I will never be able to thank them adequately. This is the kindest act any human could do for another. They are the most beautiful, selfless people we’ve ever known.”

Tisdale went viral when she published an essay in New York Magazine’s The Cut titled, “Breaking Up With My Toxic Mom Group.” It’s since been speculated Tisdale was referring to Duff and Moore’s crowd, especially when Duff’s husband chimed in and poked fun at Tisdale’s article. (Tisdale did not name her former friends in the essay.)
“They all feel blindsided and hurt by Ashley speaking out the way she did,” a source close to Duff and Moore’s circle exclusively told Us Weekly. “From their perspective, they believed the group was supportive and coming from a good place, and they never thought there was any bad intent behind how things played out.”
The insider added, “The moms insist there was no ‘mean girl’ behavior and say they were genuinely trying to be there for one another during a really vulnerable time in all of their lives.”
January 2026
Duff released the music video for new single “Roommates,” prompting public praise from Moore.
“Proud friend alert!! This song is a BOP and I can’t wait for the rest,” Moore wrote via her Instagram Stories, referring to Duff’s upcoming album, Luck … or Something. “Go @hilaryduff!”
Duff reposted Moore’s upload onto her page.
