Mabel Lowe has shared a loving tribute to her younger sister Fiona, who died at 13. The eldest daughter of actor Chad Lowe and producer Kim Painter posted childhood photographs on Instagram on October 3, 2026, days after her parents announced the loss.
The post centers on the sisters’ bond and Mabel’s promise to remember Fiona. It gives readers a glimpse of their childhood together while leaving the family room to grieve privately.
Mabel Lowe remembers her sister
In Us Weekly’s report on the Instagram tribute, Mabel, 17, expressed her love for Fiona and her hope that her sister was at peace. One sentence captures the heart of her message: “I will honor you forever and keep your memory alive.”
Rather than sharing a formal portrait alone, she included photographs from their years growing up together. The images accompany a message of affection from an older sister mourning a deeply personal loss.
The family’s announcement
Chad Lowe and Kim Painter announced Fiona’s death on Tuesday, September 29. Their joint statement described a smart, creative girl who loved dancing and was cherished by her parents and sisters.
They asked for prayers and privacy and directed people facing mental health challenges to the 988 Suicide & Crisis Lifeline. Our earlier coverage of the family’s statement about Fiona Lowe provides context for that announcement.
Fiona’s sisters are Mabel Lowe and Nixie. The public tributes remember her within that family, as a daughter, sister and granddaughter, rather than reducing her life to the circumstances of her death.
A grandfather’s remembrance
Us Weekly also reported that Fiona’s grandfather, Chuck Lowe, posted a remembrance the day after the announcement. His brief message was another expression of love for the granddaughter the family was mourning.
Mabel Lowe’s message adds another family’s voice to the public remembrances. None of those posts changes the parents’ request for privacy, and readers should avoid treating their photographs or words as an invitation to speculate.
Support and respect for privacy
People following the story can acknowledge the loss without asking relatives for more details. For readers supporting someone in their own lives, our guide to supporting someone who is grieving offers a starting point for thoughtful conversation.
