The former X Factor star has been ordered by the pair to recreate his Sexy And I Know It, which sees him dance topless and perform a tricky seat lift with professional partner Jodeyne Higgins.
But speaking to The Sun, Chico admitted he was nervous about performing the routine again.
He told the newspaper: "I got a phone call and they said, 'Chris and Jayne want you to do Sexy And I Know It for the tour and could you do it for the final?' I thought, 'Here we go... people are going to say he can't skate, he's getting his body out for the vote,' and I've had a real problem with it."
But despite the doubts, Chico has agreed to perform the routine.
He explained: "Then I thought to myself, 'Let the voting public decide.' So I went on Twitter and said, 'I can't really tell you what I am doing but what's your favourite routine if I had to do it?'
"Around 99.9 per cent of them said Sexy And I Know It. So I thought, 'OK, let's do it then.'"
However with just 24 hours to go until the big night, the singer confessed he's been having nightmares about the show.
"I have a back problem that I've got from the show and in all the weeks it had to come back – it's this week," Chico revealed the tabloid. "I can't do one lift, I've had to change it because of my wrist – it's the seat lift where your hand is right up her bum!
"I managed to get her so far up but they wanted it travelling and turning and my wrist can't handle it so we had to change it."
Chico will be going head to head with soap stars Matthew Wolfenden and Jorgie Porter in the Dancing On Ice final, and he added: "In this final, there is no room for error.
"The skating level has come up to such an extent that one slip, one error, one fall, will highlight it to such a degree."
The show airs at 6:50PM tomorrow on ITV1.
