Her lips aren’t sealed.

Hilary Duff slammed Ashley Tisdale’s allegedly false toxic mom group claims on “Call Her Daddy” Wednesday, explaining why she felt “used” over the viral drama.

“I felt really sad. I honestly felt really sad,” the actress told podcast listeners of reading her fellow Disney Channel alum’s essay for “The Cut” in January. “I was pretty taken aback and felt just sad.”

Her first reaction was “whoa,” with the “Lizzie McGuire” alum insisting Tisdale’s claims, which ranged from “mean-girl” behavior to “high school”-like isolation, are “not true.”

“It sucks on behalf of, like, six women,” she continued, referencing Meghan Trainor, Mandy Moore and the other mothers in the A-list group.

At the time, Duff was promoting the singles from her “Luck… or Something” album, which came out Friday as the singer embarks on a world tour.

During Wednesday’s episode, the songwriter also broke her silence on her husband Matthew Koma chiming in on the scandal via Instagram Stories last month.

The 38-year-old made headlines when he spoofed Tisdale’s promo photo for her essay and supplied a scathing new title.

“A mom group tell all through a father’s eyes: When You’re the Most Self-Obsessed Tone Deaf Person on Earth, Other Moms Tend to Shift Focus To Their Actual Toddlers,” it read.

Duff confirmed that she did not know about the diss ahead of time, adding, “Honestly, everything he does makes me laugh. So I was like, ‘Oh, my God.’ But I also don’t censor him, and I don’t tell him what he can and can’t post. He is so, like, fierce for me, and I love him for that.”

Koma quickly deleted the social media upload at the time — but not before it made waves.

“Glee” alum Becca Tobin dubbed the record producer a “loser” on her “Ladygang” podcast for “jump[ing] in and “get[ting] petty.”

Tisdale’s husband, Christopher French, also stirred the pot with a pointed Instagram post, reading, “It’s your choice whether or not to engage.”

Duff stayed silent on Tisdale’s claims until an interview with the Los Angeles Times last week.

“On the days when crazy s–t happens, I go home and quiet the noise,” she told the outlet last week, calling her family time — with son Luca, 13, and daughters Banks, 7, Mae, 4, and Townes, 1 — the “purpose of life.”
