Simon Cowell and Paula Abdul spent the night in a haunted hotel.

The 'x factor' judges checked into The Stoneleigh Hotel & Spa in Dallas but they had no idea about its reputation and while fellow judge L.A. Reid checked out almost as soon as he arrived, Simon and Paula stuck it out a little longer.

A source told Us Weekly magazine: "L.A. didn't even know the story of the Ghosts; he just couldn't be inside the hotel. He was first to check in and left before The Others arrived, saying it had a 'weird feeling about it.' Everyone joked he was being a diva, but when they heard about the hotel really being haunted they just thought he was smart!"

While Paula - who reportedly experienced her bathroom's taps being turned on and off on their own - was left scared by the experience, sources say Simon enjoyed the spooky goings on.

The source added: "All the other judges were freaked out and insisted on changing hotels or rooms, but Simon was quite happy with the ghosts. He was fascinated by them. It wouldn't surprise anyone if he insists on staying in only haunted hotels in future!"
