The set of actress Jennifer Love Hewitt's new hit US TV show GHOST WHISPERER has become a portal to the nether world.

In the show, Hewitt plays a woman who can communicate with the dead, and now ghosts are literally coming back to haunt her on the set.

The actress admits there have been some inexplicable supernatural moments on the set, but one in particular gave cast and crew the chills.

She explains, "We did a scene where we were filming this staircase and there were these little boys who were kind of burning in an orphanage.

"A woman showed up at the bottom of the stairs when we played the footage back. She was just standing there."
