Caroline Flack says a ghost brushed against her bum as she filmed the judge’s house stage on The X Factor.

The Xtra Factor host and Cheryl Cole joined Gary Barlow and the over-25s at 16th Century Boughton House in Northamptonshire, and she is convinced a spirit groped her.

Flack, 32, told The Sun: “I don’t believe in ghosts. I’m a real sceptic. But I felt something brush past me and there was nobody else in the room. It was weird.

“Later on, I thought I saw something move in the mirror.”

Cole, 29, joked that it was the “ghost of Simon Cowell” in a dig at her former boss, but even Gary, 41, agreed something “creepy” was going on at the property.

He explained: “There were parts of the house that went really cold even though it had been hot outside – and there were some pretty weird creaks and groans going on.”
