Hilary Duff's sister issues subtle response to Ashley Tisdale's 'toxic mom group' essay

Hilary Duff's sister has seemingly interjected her own thoughts after the Lizzie McGuire actress was caught up in Ashley Tisdale's ‘toxic’ mum group debacle.

Ooh, there’s more than champagne popping off in the New Year, as celebrities are now hashing it out in public.

On New Year's Day, the High School Musical actress, 40, dropped her essay in The Cut about 'breaking up with' a group of 'toxic moms' who she claims excluded her and made her feel like she was back 'in high school'.

While Tisdale didn't name any names, many fanned the flames of speculation by suggesting her essay was about a celebrity mom group that reportedly included the A Cinderella Story star, 38, and Mandy Moore, 41.

However, the 'He Said She Said' singer's representative nipped the rumours in the bud and denied that Tisdale was referring to Duff or Moore.

But a few people have publicly weighed in on the situation, including Hilary's husband, Matthew Koma, and now her sister, Haylie.

According to numerous publications, including BuzzFeed and The Daily Mail, Haylie liked Tisdale's Instagram post promoting her essay.

Rumours surrounding the sisters' relationship have been floating around for a while, with US Weekly reporting that the siblings haven't been pictured together since 2019.

While neither Hilary nor Haylie has addressed anything publicly, the Cheaper By The Dozen star mentioned 'family drama' while chatting to Rolling Stone in November last year.

She said: "I have this crazy connection with fans that I’ve known since I was 9, 10 years old, and I just want to connect with them again. We have gone through a lot of the same things — whether that’s complicated relationships, anxiety, raising kids, divorces, trying to find yourself in adulthood, family drama…

"Finally I felt safe enough and comfortable in my own family to step outside and open that part of myself up again."

In her essay, Tisdale revealed that she became aware of her exclusion 'because Instagram made sure it fed me every single photo and Instagram Story'.

"Another time, at one of the mom’s dinner parties, I realised where I sat with her, which was at the end of the table, far from the rest of the women. I was starting to feel frozen out of the group, noticing every way that they seemed to exclude me," she continued.

After being left out of another get-together, Tisdale said she texted the chat: "This is too high school for me, and I don’t want to take part in it anymore."

However, this didn't 'exactly go over well' and after one mum 'tried to smooth things over' by sending her flowers, she said they then 'ignored her' when she tried to thank her.

Tisdale said that she didn't consider any of the mums to be 'bad people', though, except 'maybe one', adding that the group's dynamic was no longer 'healthy and positive' for her.
