There are ongoing reports that Hilary and Haylie Duff are currently estranged, but the exact cause has not been shared publicly in detail by either sister.

Quick Scoop: What Happened Between Hilary and Haylie Duff?

1. The basic situation

  • Hilary Duff has confirmed that she and her sister Haylie are not close right now and are going through a serious rough patch.
  • They have reportedly not been photographed together since around 2019, and fans also noticed that their social‑media interactions dropped off.
  • Hilary’s new song “We Don’t Talk” is explicitly about this fractured relationship, which she’s described as one of the loneliest parts of her life at the moment.

“It’s definitely about my sister… the most lonely part of my existence is not having my sister in my life at the moment.” – Hilary Duff on “We Don’t Talk”

2. What Hilary has (and hasn’t) said

  • In recent interviews, Hilary has said the song reflects their estrangement but has carefully avoided giving a specific reason or timeline for the fallout.
  • The lyrics point to confusion and hurt more than a clear incident — she sings about not knowing exactly when things changed or what it was really about.
  • She has framed the song as her personal truth and set a boundary that she’s only comfortable sharing her perspective, not going blow‑by‑blow into private family drama.

3. Clues and fan theories (unconfirmed)

None of the following has been confirmed by Hilary or Haylie; it’s mostly speculation and reading between public lines, so it should be taken cautiously.

  • Some entertainment outlets and gossip accounts suggest tension involving their respective partners — Hilary’s husband Matthew Koma and Haylie’s fiancĂŠ Matthew Rosenberg — and claim they do not get along.
  • Theories about long‑standing “career jealousy” or competition between the sisters have floated around in commentary and fan videos, but these are based on interpretation, not direct quotes from them.
  • A few blind‑item style pieces and gossip videos go much further with dramatic claims, but they rely on anonymous tips and speculation rather than verifiable facts, so they’re best treated as rumor, not reality.

4. The Ashley Tisdale / “toxic mom group” angle

  • In early 2026, Ashley Tisdale published an essay about distancing herself from a “toxic” mom friend group, and online chatter heavily implied Hilary was part of that group.
  • Shortly after the essay, Haylie was seen liking Ashley’s piece and later going out to dinner with her, which many fans interpreted as Haylie “siding” with Ashley against Hilary.
  • Around the same time, Hilary’s husband Matthew Koma poked fun at the drama with a satirical “magazine cover” post, which added fuel to the narrative that there’s a wider friend‑group and in‑law conflict circling the sisters.

5. Where things stand now

  • Publicly, Hilary has focused on expressing her feelings through her music rather than blowing the situation up on social media or in interviews.
  • Haylie has not given a detailed public response or her side of the story, so we only have Hilary’s partial perspective and outside speculation.
  • For now, all that’s really confirmed is: they used to be extremely close, they’re estranged at the moment, it feels very painful for Hilary, and the specific “why” remains private.

TL;DR:
Hilary and Haylie Duff are currently estranged, and Hilary’s song “We Don’t Talk” is directly about their broken relationship. Fans and gossip sites point to possible tension involving partners and the so‑called “toxic mom group” situation with Ashley Tisdale, but the sisters themselves have not publicly confirmed any single incident as the cause, so most of the dramatic theories online are still just speculation.
