Mandy Moore is spilling some tea about the challenges of friendships amid parenthood. Does this have anything to do with Ashley Tisdale?? In Wednesday's episode of Cameron Rogers podcast Conversations with Cam, the This Is Us star revealed she's been having to "mourn" the loss of a once tight friendship! She explained: "Do you feel like you have seen friendships, sort of, take a different course?" Oh, boy...

The actress explained: "I have friends who have kids that are older, and I have found that the people I'm closest with in my life right now are people who are at the same chapter of their lives as parents. Like, we have kids the same age. I've had to sort of mourn in a way, not the loss of those friendships, but how they've changed." The podcaster agreed it's normal for parents to stick close to other moms with kids close to the same age, saying: "I have friends who have kids the exact same age as mine. I have friends who have kids that are older. ... The reality is, you're going to be more in contact with people who are your [kids'] exact age." Mandy revealed that the changing friendships have "caught [her] off guard," noting: "I've been surprised by it." She reflected: "I just assumed all of these relationships would continue to ... not that they don't serve me, but, they wouldn't be the first people I would reach out to right now when I'm like, 'Gus has changed his mind seven times about what he wants to be for Halloween.'" The A Walk to Remember alum shares August, 4, Oscar, 3, and Louise, 15 months, with her husband Taylor Goldsmith. Interestingly, Ashley's kids are about the same age. Jupiter is 4, and Emerson is 1. She shares them with her husband Christopher French. So, the kids' ages aren't why these two drifted apart - but it would certainly seem like she'd dealing with a change in that friendship, too! Elsewhere in the podcast, the Candy singer actually opened up about her now infamous mom group, including by sharing the origins! She dished: "So, I think the origin story is all kind of having pandemic babies. Hilary Duff is a very dear friend of mine. She and her husband, Matt [Koma], are very close with me and Taylor, my husband. [Duff's daughter] Mae-Mae was born six weeks after Gus, and she is the ultimate mom. She has four kids now, but at the time, Mae was her third. She was a boss. She was just like, 'We need a music class. We need community.' So she started this music class at her house and gathered a group of incredible women, and I brought a few into the fold as well." Things quickly progressed from the initial music classes: "We evolved from music class to movement class to just all hanging out. People get together for holidays, people get together for birthdays, we go to the zoo ... all the things you do collectively as a friends group." But perhaps not as "collectively" as they're making it sound?? As Perezcious readers know, in an essay for The Cut, the High School Musical alum revealed she was being left out of gatherings and slowly cut out from the group. She ultimately decided to "speak up" for herself and sent them a text removing herself from "toxic" the gap pals, claiming it was "too high school" for her. But, clearly, the women aren't so hung up on her complaints. They're still going about life as usual - and probably throwing a LOT of shade in their very active group chat! Mandy shared: "The moms chat is always popping off with questions, comments, concerns, fun gossip ... all the things. They mean everything. We all just went away a couple of weeks ago to Ojai [in California]. We did a quick little 24 hours away from our families and celebrated Hilary's birthday belatedly." The gossip must've been piping hot after they got Ashley's heated text! Oof! Listen to the full chat (below): Reactions?! Sound OFF (below)!
