'I'm A Celebrity...Get Me Out Of Here!' crew members have been spooked by ghosts at Gwrych Castle.
This year's series is being staged in the Welsh castle due to the coronavirus pandemic, and the crew has already taken to avoiding derelict parts of the building amid fears it is haunted.
A source said: "People thought they saw a figure at one of the windows a couple of nights ago - and that spot has been pretty much off limits ever since."
Production staff on the show - which is hosted by Ant and Dec - claim to have seen faces at windows and some of the crew have been insisting on moving around in groups once the natural light begins to fade.
Another source told The Sun newspaper: "The place is utterly terrifying at night.
"Several of the crew are completely horror-stricken and don’t want to go up to the castle.
"There are lots of lights on the main sets but there are also many dark areas behind the scenes and some noises are extremely spooky.
"Even staff who don’t believe in that sort of thing are reluctant to go up to some parts that were supposed to be used for running equipment and camera positions.
"If people keep getting scared, bosses are going to have to do something to combat it."
According to legend, Gwrych Castle is haunted by the spirits of its former inhabitants, like Winifred Bamford Hesketh, the Countess of Dundonald who inherited the castle from her father in 1894.
However, when she died in 1924 at the age of 64, her husband made a concerted effort to destroy her life's memory, prompting the countess to return to haunt the castle's corridors.
Meanwhile, Ofcom has received 79 complaints from 'I'm a Celebrity' viewers after Jordan North was seen vomiting on the show.
The 30-year-old radio host was sick into the bushes before he abseiled down a cliff, and the regulator subsequently received a wave of complaints.
A statement read: "Ofcom has received a total of 79 complaints for last night’s 'I’m a Celebrity….Get Me Out of Here!' of which 37 related to scenes of Jordan vomiting and 18 related to non-specific animal welfare."
