Mabel, the 17-year-old daughter of Chad Lowe, has posted an emotional tribute to her younger sister Fiona, who died by suicide at age 13.
Mabel Lowe, 17, honored her sibling by sharing a carousel of sweet throwback photos to Instagram of the two youngsters growing up and sharing everything together.
“I love you so much Fiona,” Mabel wrote in the caption of a post shared Saturday. “I wish your short time here was easier and I hope your mind is at ease now. I will honor you forever and keep your memory alive. I love you, I hope you knew just how much.”
The slideshow included cherished family photos of the sisters together at the beach, in a car decorated with birthday balloons and at home in a pet bed. Other images showed Fiona riding in a wagon, receiving a hug from her older sister while in her crib, enjoying a picnic and dancing in the studio.
Mabel’s poignant message comes as the Lowe family continues to receive an outpouring of love and tributes following Fiona’s tragic death.
Lowe’s eldest daughter, Mabel, took to her Instagram Stories on Friday to repost touching video tributes from Fiona’s former dance teacher and the youth club and camp Fiona attended prior to her passing.

Fiona, whom the actor shared with his wife, Kim Painter, died by suicide on Tuesday. The couple also have a younger daughter, 10-year-old Nixie.
The first video in one tribute was originally posted by Kendra Andrews, a teacher and choreographer at the Los Angeles dance studio Fiona attended.
In a lengthy caption, Andrews began by recalling the devastating Los Angeles wildfires that destroyed the family’s home.
“This first video was taken only a month after you lost your home in the fire,” Andrews wrote. “You came into the studio like you always did for all the years I’ve known you … excited with a beaming, bright smile and a big, warm hug for me.”
Andrews’ post also included a second video of Fiona performing the same dance after spending weeks practicing and refining the routine.
“The next video is our second rehearsal a few weeks later. You had clearly spent so much time outside of the studio working hard to fine tune and finesse. Your passion and determination were incredibly beautiful to witness,” Andrews wrote.
“I didn’t film when you performed it on stage a couple days later, as I wanted to be fully present and soak it in. I just watched from the wings, heart swelling with pride and my eyes flooding with tears of joy.
“FiFi, I love you more than words can convey. It was an honor to teach you, laugh with you, and watch you grow. Our hearts are shattered. We will never be the same without you here. I will miss you and love you forever,” she continued.

“I wish your short time here was easier and I hope your mind is at ease now. I will honor you forever and keep your memory alive,” Mabel wrote in her post on Saturday. Above, Lowe and his wife Kim Painter with their daughters Mabel, Fiona and Nixie

Andrews also shared a message of support for Fiona’s parents and sisters.
“Chad, Kim, Mabel, and Nixie…I love you and I’m thinking of you nonstop,” she wrote in closing.
Widget Works, a youth group and summer camp offering beach days, ocean activities and outdoor adventures in Santa Monica and the Pacific Palisades areas of Southern California, also shared a moving tribute to the teenager.
Mabel reposted their video of Fiona hanging out on the beach with friends and chatting about her stuffed pumpkin pillow which she had named ‘Mr Pumpkin.’
‘He’s a lopsided pumpkin,’ Fiona told the woman behind the camera with a jovial smile.
‘Thank you, Fiona. Thank you for all the beautiful years we were able to frolic, dance, laugh and love each other,’ Widget Works wrote.

‘The way they’ve handled this whole devastating experience is nothing short of remarkable. I am in awe of their spirit and resilience.’
Lowe, who was previously married to Oscar-winning actress Hilary Swank between 1997 and 2007, also insisted it was his ‘greatest joy and privilege’ being a father to the trio.
He added: ‘Helping them navigate these tough times is my sole purpose. Being their dad is my life’s greatest joy and privilege.’
