Mabel Lowe Shares a Heartfelt Tribute to Late Sister Fiona — Childhood Photos Reveal Their Special Bond

Mabel Lowe’s latest tribute to her younger sister Fiona has left a deeply personal impression, bringing together years of childhood memories in one emotional collection. The 17-year-old shared photographs of the sisters laughing, playing, dressing up, taking family outings, and simply growing up side by side. In some pictures, they are squeezed together in a chair or riding in a red wagon; in others, they are holding hands while crossing a street or enjoying a sunny day outdoors. The images show a childhood filled with ordinary moments that became precious with time. Fiona, the daughter of actor Chad Lowe and producer Kim Painter, was remembered by her family as creative, kind and passionate about dance. But the final words Mabel chose for her sister revealed just how much these memories now mean to her.

Mabel’s carousel takes an especially poignant turn as the photographs shift from the sisters together to moments featuring Fiona on her own. One image captures her carefree as a young child, while another shows her enjoying a simple moment in the back seat of a car. The final photograph places her in a dance setting, balancing gracefully as she performs a difficult pose. That image quietly reflects the passion her family had often celebrated. Fiona died at 13 on September 29, 2026, and her family asked for privacy while mourning her loss. Mabel’s tribute, however, offered a glimpse into the bond that existed long before tragedy changed the family’s life — and her caption made clear what she wanted everyone to remember.

The carousel ended with Mabel addressing Fiona directly, expressing her love and promising to honor her memory forever. Her tribute came after Chad and Kim described their daughter as a loving, smart and creative girl who was adored by her sisters and deeply loved by her parents. The family had already endured a devastating loss when their Pacific Palisades home was destroyed in the January 2025 fires, leaving them to rebuild after roughly a decade of family memories disappeared. Chad previously emphasized that, despite losing their home, the family still had one another. That sentiment has taken on an even deeper meaning now. Rob Lowe and other relatives have also rallied around Chad and Kim as they navigate this new period of grief, while the family’s earlier experiences have shown how important their support system has become.

For Mabel, the photographs appear to preserve something that cannot be replaced by possessions, a house, an estate, or anything money can provide. They capture Fiona before she became a memory: smiling on a beach, playing at home, enjoying family outings and dancing with the energy her loved ones remembered. The images also preserve the everyday relationship between two sisters who shared years of growing up together. Mabel’s promise to keep Fiona’s memory alive gives the tribute its lasting meaning. Rather than allowing the final chapter to define her sister, she chose to show the little girl, the sister and the dancer she knew and loved. For a grieving family, those small photographs may become some of the most valuable keepsakes of all.
