Mabel Lowe, the daughter of actor Chad Lowe and his producer wife Kim Painter, recently shared some sweet words in memory of her 13-year-old sister Fiona, who died on September 29.
Mabel Lowe, 17, vowed to honor her sister’s legacy by posting a tribute on Instagram on October 3. Fiona Lowe’s death was ruled a suicide, according to the Los Angeles County Medical Examiner’s Office.
“I love you so much Fiona ❤️ I wish your short time here was easier and I hope your mind is at peace now,” Mabel Lowe wrote in her post. “I will honor you forever and keep your memory alive. I love you, I hope you know how much.”
The sisters, along with Nixie, 10, are the children of Chad Lowe and Painter.
In her post, Mabel Lowe shared several photos of Fiona from her toddler to pre-teen years, as well as a video of the two dancing together in their Halloween outfits.
The emotional tribute follows a Sept. 30 statement shared by the family on Mabel Lowe’s Instagram story.
“We are deeply saddened by the loss of our beloved Fiona,” the family wrote in a statement. “She was a smart, creative and loving young girl who loved to dance.
The statement also stated that Fiona was “very much loved by her sisters and loved by her parents.”
“In fact, he was the light of our lives,” the statement said. “His passing is devastating for our entire family and we ask for prayers and privacy at this time.”
The family did not specify the cause of death at the time but encouraged those experiencing mental health issues to seek help.
“If you or someone you know is struggling with their mental health, please reach out to the 988 Suicide and Crisis Lifeline by calling or texting 988,” they wrote.
Months ago, actor Rob Lowe’s younger brother Chad Lowe shared a post to celebrate Fiona’s 13th birthday.
“Congratulations on Fiona officially turning into a teenager today!!” In November 2025, she wrote: “Keep dancing through life FiBear! I love you so much!!❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️”
According to data from the Centers for Disease Control and Prevention, suicide is the second leading cause of death in the United States among young people aged 10-14. Additionally, one-fifth of high school students report serious thoughts about suicide, while 9% say they have attempted suicide.
The nonprofit National Alliance on Mental Illness encourages individuals caring for loved ones to “seek help and support before a crisis occurs.”
“If you or a loved one begins to worry but do not feel in danger of self-harm or acting out with suicidal thoughts, then steps should be taken to find help for care and support,” the organization wrote on its website. “This help can come from a pediatrician, primary care provider, or a mental health clinician.”
