Is “We Don’t Talk” About Haylie Duff? Hilary’s Lyrics Explained

Yes, Hilary confirmed that “We Don’t Talk” is about her complicated relationship with Haylie. The lyrics point to a person with whom Hilary shared the “same home, the same blood” with.

What Happened Between Hilary Duff & Haylie Duff?

It seems that not even Hilary knows what caused her and her sister Haylie’s estrangement. As her song “We Don’t Talk” points out, “I’m not sure when it happened.”

During Hilary’s CBS Mornings interview in February 2026, the How I Met Your Father alum was asked if she’d talk about her new track with Haylie.

“I don’t know how she’ll react to it,” Hilary admitted. “But it is a really personal part of my life that doesn’t get to stay personal, so I might as well say how it is for me as an experience. … That’s all I’m trying to do. I’m not trying to say anything bad. It’s literally just my experience, and that’s really all I feel like sharing.”

Hilary went on to explain that she can only “exist as a person on my own and do what I want to do.”

“I hope that for everyone that is where I’m sitting, you have to do what you want to do and you have to do what feels good for you,” she concluded. “It’s taken me a lot of time to get there and to live that way and to not care what the noise is going to be around it and just be me.”

That March, the “Roommates” singer discussed the estrangement again during an appearance on Jay Shetty’s “On Purpose” podcast.

“It’s really hard, I think, if a family breaks apart very dramatically,” Hilary said, also referring to her parents’ divorce. “It’s hard to find your way back sometimes—some people want to and some people don’t.”
