The Only Way Is Essex's James 'Arg' Argent is confident the reality show's stars can beat the X Factor winner's single to Christmas Number One.
The cast of TOWIE are releasing their version of Wham's Last Christmas, which they will be performing live at ITV's Text Santa event at the Kia Oval Cricket Ground in London on Sunday November 27.
Arg said: "As much as I love the X Factor I don't think it's had its strongest year, and I think because of the charity we're supporting, we've got the backing of ITV1, ITV2, and all the magazines and newspapers, we've got a huge fan base.
"So we've got a good chance to get that number one spot. And why not, it's a good song. I think people will be very surprised."
The TOWIE cast will also be taking part in an attempt to break the Guinness World Record for the largest gathering of people dressed as Santa Claus at the event on Sunday.
Arg said: "I'll be very upset if I didn't have a Santa costume because I want it in my CV, not just being a Bafta award winner, but that I'm an official world record holder as well."
The reality TV star said of performing the single live: "I'm really nervous. As a kid I always dreamt of being a pop star and this is our first glimpse of pop stardom. And to perform it live in front of so many people - they said potentially there could be 17,000 people there."

Last Christmas by TOWIE will be released on December 18.

Gemma Collins(03 of14)
Open Image ModalTOWIE's token larger lady brings endless laughs. Not one to sweep things under the rug or avoid the awkward questions, Gemma once asked Greek twins Dino and Georgie if they look at each others penises. (credit:PA)

Harry Derbidge(05 of14)
Open Image Modal"Shuuuuuurp!" Harry not only has one of the best catchphrases on the show, he's also on the same level as the girls when it comes to tans, bleached hair and posing. (credit:Getty )
Mark Wright and James Argent(06 of14)

Mark Wright(07 of14)
Open Image ModalMark's been branded just about every name going when it comes to his alleged philandering, but that hasn't stopped the TOWIE girls going near him. Anyone would think he's the only man in Essex. (credit:PA)
Lydia Bright(08 of14)
Open Image ModalLydia gets credit for having the most tasteful dress sense on the show, think more Chanel and less Agent Provocateur. She's also a hero for putting up with Arg and Mark's bromance. Not one to shy away from a fight, she's pretty good at putting Arg in his place. (credit:Getty)
TOWIE girls glammed up(09 of14)
Open Image ModalSee, they can look demure. You've just got to give them a Bafta.

Joey Essex and Sam Faiers(11 of14)
Open Image ModalJoey Essex, you really can't get more Essex than him. He's also the closest thing to a male Barbie on television at the moment. Here's a rare picture of the "reem" ladies man wearing trousers and not short shorts. We think it's time he faced up to the fact that they're NEVER going to catch on. (credit:Getty)
Lauren Goodger(12 of14)
