Hilary Duff recently opened up about “family drama,” addressing longstanding fan speculation of a rift between her and her sister, Haylie.

In an interview with Rolling Stone regarding her upcoming music, Hilary revealed that she finally feels prepared to “fill in the blanks” and connect with people on a more personal level. She expressed a readiness to share experiences and emotions relevant to her current life.

Hilary shared that she and her fans have navigated similar challenges, including complex relationships, anxiety, parenting, divorce, self-discovery in adulthood, and family conflicts.

“I’ve finally reached a point where I feel secure and comfortable enough within my own family to venture out and reveal this part of myself again,” she stated.

This candid discussion follows years of rumors suggesting a sibling rivalry. The sisters, Hilary, 38, and Haylie, 40, once known for their close bond, have not been seen together in public for some time and rarely interact on social media, fueling speculation about their relationship.

Thus far, Haylie hasn’t even posted anything about Hilary’s new song.

Furthermore, they have not been seen together in public since March 2019, when they were spotted shopping in Los Angeles, Calif.

It’s unclear why the sisters are allegedly feuding, but DeuxMoi previously claimed they had a fight over Hilary’s husband, Matthew Koma, and how he doesn’t get along with Haylie or her fiancé, Matthew Rosenberg.

Fans on Reddit have also discussed various theories, and alleged Haylie wasn’t at Hilary and Koma’s 2019 wedding. Though, various reports claimed at the time that Haylie did attend the ceremony.

Reps for Hilary and Haylie didn’t immediately respond to Page Six’s requests for comment.

Duff released “Mature” — her first single in 10 years — on Friday. In her interview with Rolling Stone, she described the song as “self-talking to my younger self about an experience that we had.”

She further said the track was reflecting on the experience “and being okay with it and having a little tongue-in-cheek moment with yourself and accepting your past and being good with where you landed.”

In September, Duff revealed that she signed with Atlantic Records and has a docuseries — which will feature interviews, performances and videos from her personal archive — on the way.
