Hosted by Big Brother's Bit On The Side's Rylan Clark-Neal, Celebrity Ghost Hunt Live airs on Channel 5's digital channel 5STAR this evening (September 13) from 9PM.
Alongside Chris and Charlotte will be Ex On The Beach's Charlotte Dawson, Celebrity Big Brother winner Stephen Bear and Real Housewives of Cheshire’s Ampika Pickston.
In a 90 minute one-off special, they'll film a spooky ghost hunting trip with Rylan at the 'haunted' Harwich Fort in Essex.
Rumour as it that the fort is haunted by a pregnant teenager who previously died there.
Alongside the celebs, the show will also include 'experts' like psychic Ian Lawman and a pair of paranormal investigators, Paul Hobday and Chris Howley.
And they'll have some "high tech" gadgets to hand including a so-called 'ghost audiorecorder' and 'ghost tracker' glasses to hunt down the spirits.
An insider told The Sun newspaper: "Chris Hughes is going to be hysterical – he was the easily the most scared on Love Island."
The source claimed: “There will be no funny business with this show – it will be a genuine ghost hunt. And there’s no hiding as it will be broadcast live.
“Some of the high tech equipment is going to be used so the celebrities can become top ghostbusters.
“It’ll be something ghost hunting fans have never seen before.”
Celebrity Ghost Hunt Live will air tonight on 5Star at 9PM until 10:30PM.
