The former 'X Factor' contestant has been lined up to join the programme after Prince Andrew's ex-girlfriend Koo Stark made a shock departure just days before the launch.

The news that Christopher will be entering the reality television show will please fellow contestant Danniella Westbrook as the pair are good pals, the Daily Star on Sunday newspaper reports.

Meanwhile, host Emma Willis previously revealed the show's bosses are going for a Vaudeville theme this year.

She shared: "It's going to be quite a theatrical and dramatic theme. The house will look theatrical and plush. And the garden is like an old Whitechapel street, Jack the Ripper-style, which will be amazing.

"We're going to basically see an amazing period drama play out over the weeks. It's about testing how good they are as actors. Will their masks slip? There's always going to be a sinister side to any 'Big Brother' theme and I'm sure there was a sinister side to Vaudeville. So it's going to be Big Brother being naughty and messing with them."
