The TV presenter and sports commentator, 54, will be performing an American smooth to a rendition of White Christmas by Otis Redding with new professional dancer Jowita Przystal. But he says he hasn’t been getting fully into the Strictly spirit. He says: “I’ve been asked twice if I want a fake tan and twice I’ve refused. My outfit isn’t really glittery and its very comfortable, I might take it home with me. I got these new dancing shoes and they’re almost completely knackered already, in only ten days.”
He also reveals he won’t be watching the show either, which airs on Christmas Day.
Asked what he will be doing, he adds: “All I know is I’ll be going for a walk when the Strictly Christmas Special is on as I can’t stand watching myself.”
Chiles said his family and friends were “horrified” when he first told them he was performing in the special.
He admitted he too was “terrified” and “full of regret” when he first began rehearsals but now feels the experience has been a “real privilege”.
Discussing his family and friends’ reaction, he said: “They were absolutely, to a man and woman, horrified!
“Even though my mum’s a massive fan of the show, she said, ‘Oh God!’
“But then as soon as we sent them the first videos from training they all went, ‘Oh, alright, he might not be horrendous after all!”’
Chiles, who previously co-presented both The One Show and Daybreak with Christine Lampard, added: “If you’d asked me that question 11 days ago, I’d have said absolutely terrified and full of regret, remorse and wanting to leave the country!
“I might feel like that after the show goes out … you never know!
“But, honestly, I wouldn’t have missed it, it’s been a real privilege, and I’m not just saying that, to meet Jowita, work intensively on something and just focus on that.
“Everyone is so flipping nice, I never use the word “vibe”, but the vibe is fantastic!”
The TV star revealed he would previously only dance by himself without a mirror present otherwise he would be “filled with shame and paralysed”.
Przystal was among the new professional dancers to join the show this year, with Chiles being her first celebrity contestant as she was not paired up with one during the recent series.
She added: “Adrian is an amazing student, I couldn’t ask for a better one as my first experience partnered with a celebrity.
“Adrian is such a gentleman, literally he’s so sweet and kind. He always listens and never questions me.
“It sounds awful but he does whatever I want during rehearsals! I even got him smiling!”
Chiles added that he had been inspired by Przystal’s attitude and planned to try and be “more positive and enjoy things more” in the New Year.
“Dread and doubt gets you nowhere. I’m 54, it might be too late to alter my mental state but this has been a wake-up call to actually just do that. I’m serious about that,” he said.
