Fright night: The X Factor finalists get a scare at the London Dungeon last nightAs the X Factor finalists prepare to show their dark side on Saturday's show, what better way to get them into the Halloween spirit than a visit to the London Dungeon.
The 11 remaining acts ended up scaring themselves silly as they took time out of rehearsals last night for a few hours of ghoulish fun in the popular attraction.
Their late night antics in the museum were filmed by the ITV2 crew for X Factor spin-off The Xtra Factor.
After checking out the various spooky exhibits, the wannabes posed for a group shot with members of Belle Amie putting their heads in the stocks.
Some of the group braved the London Dungeon's new Extremis ride, which sees seated riders plummet into a dark gloom from a great height at speed.
Embracing the scary nature of the evening, Katie Waissel posted several photos of the night on her Twitter page.

She wrote: 'Just been to the London Dungeons with Xtra Factor and the gang!! I scarpered so fast I left my lace behind.'
In one shot entitled 'now THAT is a chair!', she draped herself across an ornate chair covered in dragons, spikes and gargoyles.
As well as their visit to the Dungeon, the group have also been trying on costumes ahead of Saturday's live show, which is set to have a Halloween theme.

He told the X Factor website: 'Today we are routining songs for this weekend. I'm really excited about week four. I've been offered the most massivest (sic) song ever in the world. So I'm really excited. It might be another intense one, so Cheryl might not be happy.'
Judge Cheryl Cole incurred boos from some of the audience last week when she told Aiden she found him quite 'intense' on stage.

She explained: 'This weekend's going to be a massive shock and I hope everyone is prepared for it because everyone is used to me being a bad girl rapper.
'I'm going to twist it up a bit and prove to the other people that maybe haven’t liked me as much as my supporters have, to think that actually I'm an alright singer.'
