Ashley Tisdale is learning the hard way that, when you throw s–t at a fan, it usually comes back and hits you in the face.

The “High School Musical” star wrote a now infamous essay, published January 1 on The Cut, about breaking up with her “toxic” mommy group.

“I thought I found my village. Instead, I was back in high school,” the headline read.

I’m certain the 40-year-old mom-of-two thought this revelatory piece would make her seem relatable to readers of her lifestyle blog, “ByAshleyFrench.com,” where she recently posted about the “Best Ever Vegan, Gluten-Free Cinnamon Rolls.”

After all, juicy stories about mommy culture are hot pop-culture fodder. There are novels and TV series devoted to the catty dynamics of such groups.

But one doesn’t need to be detective Poirot to guess the identities of her tale’s villains. For the last few years, Tisdale’s crew — the ones who allegedly iced her out — splashed group photos of themselves (mostly in matching robes or sweats) all over social media as a testament to their mommy bond.
