The comedian has filmed a number of hilarious sketches, which will air during the show on Wednesday 31 December.
Chatty Man host Alan donned a white crop top, knee high boots, a brunette wig and a slick of red lipstick to disguise himself as Cheryl in the sketch titled: 24 Hours in Celebrity Police Custody.
Alan's outfit mimics Cheryl's X Factor performance of 'I Don't Care', which aired in November.
The sketch synopsis reads: "The first celebrity offender to appear in this episode is Cheryl Cole, who tries to cheat her way out of her deception sentence for miming on The X Factor by stating a ridiculous fake name: Cheryl Fernandez-Versini. When up for questioning, Cheryl proves her tough Geordie persona by denying all charges and refusing to comply, choosing instead to try and dance her way out of the situation."
After the success of Alan's 2013 New Year's spectacular, he will once again be running riot around Channel 4 HQ with lots of celebrity guests, unpredictable madness and party games.
Alan will be joined by a host of stars in the studio including Jonathan Ross, James Corden, Seann Walsh, Alesha Dixon, Mark Wright and Caroline Flack.
Meanwhile, stars of the recent I'm A Celebrity... Get Me Out Of Here! series - Vicki Michelle, Jimmy Bullard and Jake Quickenden - will be manning the bar for the night. Tulisa and Professor Green will provide the live music.
Alan Carr's New Year Specstacular airs on Wednesday 31 December at 9pm on Channel 4.
