Katie Slaton, who appeared on multiple episodes of 1,000-lb Sisters alongside her cousins Tammy and Amy Slaton, has died at the age of 37 after being diagnosed with stage 4 cancer.

Tammy and Amy’s sister, Amanda Halterman, announced the news on Instagram on Wednesday.

“It is with a completely crushed heart and spirit that I have to post this. My little cousin went to sit at the feet of Jesus yesterday,” Amanda wrote alongside a photo of them both. “She was a force to be reckoned with and showed love that was accepting and given freely. She was the life of the party and my best friend.”

“I know both our grandparents and friends was there to welcome you home,” she added. “Please pray for my aunt, uncle and cousins but mostly for the babies and for Natalie to be strong. Please pray for everyone who loves her. Thank you all who has come out and supported her. #cancerscks.”

Tammy and Amy have not yet spoken publicly about Katie’s death.

Katie’s obituary page on Whitsell Funeral Home’s website confirmed that the late 1000-Lb Sisters star passed away Monday, August 25, at Linda White Hospice House in Evansville, Indiana.

A funeral service will be held at 1 p.m. on Friday, August 29, at Whitsell Funeral Home in Morganfield, Kentucky, per her obituary.

Back in January, Tammy took to Instagram to detail her cousin’s cancer battle and to ask for support from the TLC reality show’s fans.

“Y’all I’m so sorry to be asking a big favor like this but if anyone can help, even if it’s a dollar would help my cousin out so much,” she wrote. “She has been on my show but this is something new. Our family just found out about her having cancer.”

“Our fans have been there for us for so long now and y’all mean the world so any act of kindness is and will be greatly appreciated,” Tammy added. “Thank you so much and before anyone asks, yes I’ve donated myself.”

Katie was diagnosed with stage 4 gastric adenocarcinoma, a rare type of stomach cancer, earlier this year and had been receiving chemotherapy in the months that followed.
