The 'TOWIE’ star is expected to be joined by former 'I’m A Celebrity... Get Me Out Of Here!’ winner Vicky Pattison and radio DJ Nick Grimshaw on the programme, after they were spotted outside the London studio where the show is being filmed.

A TV insider told The Sun newspaper's TV Biz column: “The series will be the first of its kind, it’s incredibly snidey - but bosses believe it will be a hit.

“The celebrities involved have enjoyed using their experiences on reality shows to good effect, bidding to get the result they all need.

“It’s like two games are going on at once, one inside the house, the other between the celebs.”

‘Alan Must Win’ will feature a bunch of celebrities living inconspicuously next to a 'Big Brother'-style house full of contestants eager to win a prize.

However, the deceived contestants don’t know that the game has been rigged in favour of Alan to win.

Celebrities will have complete control of the format, introducing twists and turns in the game.

E4 boss Mel Bezalel added: “At E4, we’re completely obsessed with reality TV which drives viewing on All 4. We’re excited about taking the genre in a completely new direction.

“This is a show that engages celebrities in an entirely different way, using their unique skillset and experiences to manipulate gameplay - with entertaining and surprising results.

“This is a TV event not to miss. We can’t wait, and neither can ‘Alan’. Whoever Alan is, he’s going to have a blast.”
