• For most of their lives, Hilary and Haylie Duff were inseparable. When they were child actors navigating Hollywood together, Haylie guested on Hilary's Disney comedy series Lizzie McGuire; voiced Isabella in The Lizzie McGuire Movie and co-starred with Hilary in Material Girls. Publicly, they were the poster children for sisterhood, a team that could do red carpets, playdates, and brand events with equal aplomb, all while building a little village of shared motherhood.
  
  But adulthood complicated things. Around the time of Hilary's 2019 wedding to Matthew Koma, cracks appeared, and the sisters became estranged. "We Don't Talk" is Hilary's candid, mid-tempo ballad confronting the weird, dizzying reality of that loss.
• Duff confronts how disorienting it feels when people ask about Haylie and she realizes she no longer knows the answers, circling back to the plain, painful refrain that "we don't talk" anymore. In an interview with CBS Mornings the singer-actress said, "Absolutely the most lonely part of my existence is not having my sister in my life at the moment."
  
  It's reminiscent of other sibling estrangement songs like Rufus Wainwright's "Martha," that mix of private pain and public reflection.
• "We Don't Talk" appears on Duff's 2026 album Luck… or Something as one of the project's most personal, emotionally raw tracks, expanding the album's theme of grown-up relationships beyond romance into family bonds.
  
  Duff wrestled with whether to include such a raw song on the album but decided to do so after realizing that "so many people" have had similar fallings-out with siblings. "It's my truth," Duff explained. "It was honestly healing to say. It's hard to watch your life unfold on the internet sometimes with talking heads on TikTok speculating... sometimes they're wrong, and sometimes they're right. All of that is a crazy thing to process."
• Duff co-wrote the song with her husband Matthew Koma and with Dan Book (Hot Chelle Ray's "I Like It Like That," Blink-182's "Dance With Me").
• Production was handled by Koma and Ben Phillips, Hilary's ongoing collaborators throughout Luck… or Something. They let the confessional lyrics sit front and center over an understated arrangement.
• Duff debuted the song live in London in January 2026 ahead of the album's release, making it one of the first new tracks fans heard from her comeback era and immediately fueling speculation about its subject.
