The 36-year-old model, whose house is on renovation currently, said she wants to call in a medium as she and Hayler keep hearing unusual sounds and smelling strange scents, reported Contactmusic.
"Kieran keeps smelling cigarettes and I Googled it and spirits normally smell of smoke and flowers. I am getting a medium in. Because we're knocking things down, we're disturbing the spirits. I am 100 per cent sure there's a ghost," she said.
However, not all the mysterious goings-on can be attributed to a ghostly encounter.
"The other day Katie woke up at 4am swearing blind she could hear a ghost but it turned out to be Kevin the dog outside our room!," she added.
