Katie Slaton, cousin of "1000-Lb. Sisters" stars Tammy and Amy Slaton, has died at 37 after being diagnosed with stage 4 cancer.

Tammy and Amy's sister, Amanda Halterman, announced Katie's death in an Instagram post Tuesday, Aug. 26.

"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," Halterman captioned a photo of her and Katie Slaton. "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."

According to an obituary, Katie Slaton, a Kentucky native, died Aug. 25 at a hospice in Indiana.

She continued: "I know both our grandparents and friends was there to welcome you home. 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."

Katie Slaton made appearances in TLC's "1000-Lb. Sisters" alongside her cousins, most notably in Season 5. The series' seventh season wrapped in June.
