Married at First Sight UK host Mel Schilling has sadly passed away. She was 54. Her husband, Gareth Brisbane, shared the news via her Instagram page, revealing the TV star died peacefully on Tuesday while "surrounded by love." Her death comes after a three-year battle with colon cancer, which she was first diagnosed with in 2023. She had surgery to remove the cancer, but in 2024 "small nodules" were discovered in her lungs. She had just announced her health condition was terminal on March 12. Oof.
