Here’s what we actually know about Haylie’s life, relationships, and the rumored feud.

Nine key biographical facts, one pattern: Haylie Duff’s professional milestones are well-documented, but the personal details that drive public curiosity remain scattered across tabloids, social media, and rare interviews.

The biographical table below compiles the core known data from authoritative sources.

Does Haylie Duff Still Talk to Her Mom?

• Mother Susan Duff: Both Haylie and Hilary share the same mother, Susan, who was married to their father Bob Duff. (People)
• Reported estrangement: Multiple outlets have suggested that the sisters’ relationship with their mother is complicated, but neither Haylie nor Susan has made a public statement confirming a complete cut-off. (Us Weekly)
• Hilary’s perspective: In February 2026, Hilary Duff described family dynamics as “the most lonely part of my existence,” referencing the sister rift but not directly discussing their mother. (People)

Bottom line: The public record shows a strained family network, but factual confirmation of whether Haylie speaks to her mother remains absent from all reliable sources.

The pattern: The absence of a statement from Haylie or Susan keeps the question unresolved for now.

Did Haylie Duff Attend Hilary’s Wedding?

• Wedding date: Hilary Duff married musician Matthew Koma on December 21, 2019 in Los Angeles. (Wikipedia)
• Attendance reports: Several outlets reported that Haylie was present at the ceremony. The wedding was described as being filled with “beautiful memories,” suggesting a warm family atmosphere at the time. (IMDb (entertainment news))
• Current relationship: Despite that attendance, the two sisters have not been publicly seen together since 2019. Hilary’s 2026 song “We Don’t Talk” is widely understood to be about Haylie. (People)

The implication: The wedding attendance confirms a functioning relationship in late 2019, but the silence since then suggests something shifted dramatically in private.

Is Haylie Duff Still with Matt Rosenberg?

• Relationship timeline: Haylie and Matthew (Matt) Rosenberg began dating around 2007 and got engaged in 2014. (Us Weekly)
• Children: They share two daughters: Ryan Ava Erhard Rosenberg (born May 11, 2015) and Lulu Gray Rosenberg (born June 5, 2018). (People)
• Split: In early 2026, it was confirmed that the couple had ended their 12-year engagement. A representative told Fox News that “they ended their relationship around the first of the year” and asked for privacy “to protect their young daughters.” (Fox News)
• House sale: The duo had listed their Austin mansion in 2024 for $3.3 million, eventually selling in April 2025 for $2.7 million — a financial signal that their shared life was unwinding. (MarketWatch)

The catch: The absence of a divorce process means there are no legal documents to clarify what happened.

Why Did Haylie and Hilary Duff Fall Out?

• Rumored feud: Reports of tension between the sisters have circulated for years. The absence of joint public appearances since Hilary’s 2019 wedding fueled speculation. (People)
• Hilary’s admission: In February 2026, Hilary confirmed the rift during an appearance on CBS Mornings, saying the situation is “the most lonely part of my existence.” She also stated that her song “We Don’t Talk” is about her sister. (People)
• Possible causes: Neither sister has listed specific reasons. Theories include career competition, parenting differences, or fallout from Hilary’s marriage to Matthew Koma — but none are confirmed. (Us Weekly)

The pattern: The silence from Haylie’s side is itself a signal. A public figure who chooses not to respond to a sibling’s public comments is likely preserving either privacy or the separation itself.

Why Did Haylie Duff Never Get Married?

• Engagement: Haylie and Matt Rosenberg got engaged in 2014, but no wedding date was ever announced. (Us Weekly)
• Legal status: The couple remained engaged for 12 years without ever marrying. After the split, a representative confirmed they “never officially married.” (Fox News)
• Possible reasons: No official explanation has been given. Speculation ranges from career commitments to family priorities, but no confirmed insight exists. (People)

The trade-off: Staying engaged rather than married allowed the couple privacy around their legal arrangement — but it also meant that when they split, there was no divorce process, only a personal ending without legal entanglements.

What’s Confirmed and What’s Still Unclear

Key Quotes

The pattern that emerges is one of deliberate privacy. Haylie Duff has chosen to live outside the celebrity machine — raising her children in Texas, avoiding interviews, and letting the public conversation about her personal life flow one-sidedly. For Haylie, the path forward means co-parenting two daughters while the glare of her sister’s music keeps the rift in the headlines. The cost of that privacy: the public will likely never know the full story.
