What Caused Hilary Duff & Haylie Duff's Feud? The Drama That Started It All

That Hilary Duff and Haylie Duff are feuding is a fact many millennial women have sadly come to terms with, but that doesn’t mean we don’t still have questions about where things went wrong for our beloved Material Girls.

Hilary, 38, shared a rare comment about her strained family dynamics with her father and her older sister in a February 17 interview with Glamour. “That’s my family. Those are the people that affect you the most, take up the most space naturally as a human who’s born into something,” she said after the release of her new song, “We Don’t Talk,” which is about her estrangement from Haylie. “Just because you’re born into a family doesn’t mean that it always stays together.”

What Caused Hilary & Haylie Duff’s Feud?

Hilary and Haylie Duff haven’t been photographed together since 2019, prompting speculation about what caused the once-close sisters to fall out. While Haylie and Hilary have never addressed the root of their estrangement, a source alleged to DeuxMoi that Hilary’s husband, Matthew Koma, and Haylie’s fiancé, Matthew Rosenberg, “don’t get along,” driving a wedge between the sisters.

However, over the years, more has come to light about the sisters’ rift. Read on for more.

Hilary Was Last Linked to Haylie at Her 2019 Wedding

In December 2019, Hilary married husband Koma in an intimate ceremony at their Los Angeles home. Reports initially claimed that Haylie skips the low-key affair, but this was swiftly debunked by a source who told People, “Her sister Haylie was very involved in the wedding prep too. Hilary and Haylie are very close.”

After this, the pair stopped interacting on social media, despite still following each other.

In June 2021, Haylie and Rosenberg, along with their two kids, relocated to Austin, Texas, just a few months after Hilary and Koma welcomed their second daughter—they also welcomed a third daughter in 2023 and share Hilary’s son from a previous relationship.

Per Jezebel, speculative rumors allege Haylie is a Republican while Hilary is a Democrat, another supposed factor in their feud. Neither sister has publicly discussed their political views.

After years of speculation about the sisters, Hilary hinted at a feud for the first time in a November 2025 interview with Rolling Stone, while revealing the themes of her upcoming music.

“I’m ready to fill in the blanks and share with people and connect with them on the level of now,” she said. “My fans have gone through a lot of the same things, whether that’s complicated relationships, anxiety, raising kids, divorces, trying to find yourself in adulthood [or] family drama.”

Fans quickly connected the comment to her rift with Haylie.

Hilary made headlines in January 2026 after Ashley Tisdale’s viral essay for The Cut about leaving a “toxic mom group” that fans speculate included Hilary, Mandy Moore, and Meghan Trainor. Hilary’s husband as good as confirmed her involvement with a savage response to Tisdale.

In a surprise twist, Haylie “liked” Tisdale’s Instagram post about the essay and later posted about hanging out with the High School Musical actress.

Hilary Appeared To Reference A Feud With Haylie & Her Dad In Her New Music

In new songs from her 2026 album, luck… or something, Hilary sings about rifts with Haylie and her father, Bob Duff.

On “We Don’t Talk,” Hilary sings, I’m not sure when it happened, not even sure what it was about / If I did something different, would you feel something different? Would you at least let me hear you out?” She later refers to her rift with Haylie as an “emotional eviction.”

On “The Optimist,” Hilary sings, “I wish I could sleep on planes, and that my father would really love me.”

Hilary and Haylie’s father was married to their mom, Susan, for 20 years before a years-long divorce battle. In 2008, Bob was sentenced to jail time for contempt of court for selling family assets without approval. “Susan was very consumed with the girls’ careers…We simply grew apart,” he told Inside Edition in September 2008. “I was unfaithful to our marriage. I feel very badly about that and the effect that it had on the girls.”

While discussing the songs, Hilary told Glamour, “You can only control your side and your street…. I’ve had a very complicated life, and my parents had a very complicated thing. I know it’s not rare, and I think it goes back to the theme of, Why share now? I guess I just felt ready.”
