The same website also highlighted her work as an author, speaker, and ordained evangelist. Over the years, she appeared on programs such as “The Today Show,” “Entertainment Tonight,” and “The Oprah Winfrey Show,” sharing her story of recovery and faith.

She also authored the memoir “Father Does Know Best: The Lauren Chapin Story” and became involved in charity work supporting underprivileged children.

The Private Health Struggle

While his initial message referred only to a long and difficult battle, Matthew later elaborated on the circumstances of the star’s passing, writing in the same Facebook post: “My mother Lauren Chapin passed away from her battle with cancer tonight .”

A Fellow Colleague Pays Tribute

As news of her passing spread, actress Erin Murphy publicly honored Lauren’s memory. In a brief message on Facebook, she expressed sadness over the loss of her friend and included a broken heart emoji.

She also shared photos that appeared to show them together in recent years, along with childhood images reflecting on Lauren’s life.

Lauren’s passing comes during a difficult period for fans of classic television.

Just days earlier, Robert Carradine, the actor who charmed generations from college comedies to Disney Channel living rooms, died at 71 on February 23, 2026.

A Shocking Goodbye No One Saw Coming

The beloved performer — best known for “The Long Riders,” “Revenge of the Nerds,” and “Lizzie McGuire” — died by suicide, according to his family. The devastating news was first reported by Deadline.

Robert wasn’t just a Hollywood staple; he was part of a legendary acting dynasty and, as his older brother Keith Carradine described, the “bedrock” of the family. But behind the warmth and humor that lit up screens for decades was a private struggle few fully understood.

In a statement shared with Deadline, his family revealed the depth of that battle. “It is with profound sadness that we must share that our beloved father, grandfather, uncle, and brother Robert Carradine has passed away. In a world that can feel so dark, Bobby was always a beacon on light to everyone around him [sic],” the statement reads.

Behind the Smile That Lit up Hollywood

They continued with words that have since struck a chord across Hollywood: “We are bereft at the loss of this beautiful soul and want to acknowledge Bobby’s valiant struggle against his nearly two-decade battle with Bipolar Disorder.“

The family also made it clear they hope his story sparks change.

“We hope his journey can shine a light and encourage addressing the stigma that attaches to mental illness,” they added, before asking for privacy as they grieve this “unfathomable loss.”

Keith also spoke candidly about his brother’s illness, something the family says should not be hidden in shame. “We want people to know it, and there is no shame in it,” he asserted. “It is an illness that got the best of him, and I want to celebrate him for his struggle with it, and celebrate his beautiful soul.”

He described Robert as “profoundly gifted,” remembering how funny, wise, and “utterly accepting and tolerant” he was.

What Robert’s ‘Lizzie McGuire’ TV Family Had to Say

For many millennials, though, Robert will always be Sam McGuire: Lizzie McGuire’s lovable, steady dad on the Disney Channel hit show.

Following the announcement that Robert died by suicide after his 20-year battle with bipolar disorder, the “Lizzie McGuire” cast shared their heartbreak and remembered his “constant fatherly like [sic] support” on set, according to Deadline.
