Mabel Lowe is remembering her late sister Fiona on an emotional day.

Nearly two months after Chad Lowe and Kim Painter’s middle child died by suicide at the age of 13, her older sister shared a touching tribute to Fiona on what would have been her 14th birthday.

“Happy birthday fiona,” Mabel wrote on her Instagram Stories Nov. 14 alongside a photo of her younger sibling smiling while holding up a Harry Potter movie poster, “I miss you.”

The 17-year-old continued to honor her late sister, sharing sweet photos of her and Fiona, including a throwback shot of the two holding hands while wearing matching shirts with an illustration of a cat on them.

Over the photo, Mabel referenced both of their respective zodiac signs, including a Scorpio and Taurus emoji, adding the word, “forever.”

The teen also looked back at more memories, sharing a pic of her and Fiona wearing cowboy hats and another more recent photo of the sisters posing for a mirror selfie.

On Sept. 29, Chad and Kim announced Fiona’s tragic death in a statement to People, that they were “deeply heartbroken by the loss,” remembering the teen as a "loving young girl who was smart, creative, and loved to dance.”

The couple—who also share daughter Nixie, 10—added that Fiona was “adored by her sisters” and “deeply loved by her parents,” describing their late daughter as “the light of our lives.”

“Her passing is devastating for our entire family and we ask for prayers and privacy at this time,” the pair wrote. “If you or someone you know is struggling with mental health, please reach out to the 988 Suicide & Crisis Lifeline by calling or texting 988.”

Fiona’s manner of death was ruled a suicide, according to the Los Angeles County Medical Examiner, per People.
