Strictly Come Dancing stars are convinced the show is haunted following a series of unexplained bumps.

The hugely popular BBC show returned with live action this week, as this year’s celebrity contestants took to the floor to be judged for the first time.

But a number of the Strictly stars, including Motsi Mabuse and Craig Revel Horwood, have reportedly expressed concerns about the studio over fears it may be haunted.

A source told The Sun on Sunday newspaper: "A number of them have experienced things that they cannot explain."

The stars have complained about unexplained bumps and other incidents.

They have, in fact, already urged producers to hire a spirit guide or psychic healer to address their concerns, after the new series launched on the BBC.

The insider shared: "To say some of the professionals are hysterical at the thought of having to go back and spend large amounts of time at Elstree is an understatement.

"A number of the dancers and even one or two of the judges have experienced things that they cannot explain.

"They’re so concerned they are going to have a meeting with producers, possibly next week, to explain their fears and get help.

"Several of them are going to ask the BBC execs to bring in an energy healer or an expert in ridding buildings of spirits and the paranormal.

"You could say it’s regarded as the real curse of Strictly."

What's more, the dancers and their celebrity partners have been sharing ghost stories ahead of the show's Halloween special.

The source added: "Some of them have made it very clear they believe in the paranormal.

"They’ve been telling their ghost stories to each other and getting really spooked.

"But at the same time there is a genuine desire to call in an expert who can help relieve their fears."

Strictly Come Dancing returns this weekend, airing on BBC One and BBC iPlayer at 6.20pm on Saturday, September 30.
