The Girls Aloud star is said to be training for a routine involving wires during her salsa on Saturday's show, according to The Sun.
Sources have claimed that the singer is "proud" to become the second celebrity to attempt the routine following Ann Widdecombe's infamous dance in 2010.
Widdecombe will return for a Children in Need special of Strictly with Russell Grant on Friday, November 16.
Walsh has also denied reports that boyfriend Justin Scott is jealous of her dance routines with partner Pasha Kovalev.

"It's everybody else who seems to have the issue. This is what I do – I'm an actress as well. I've done loads of things with people on stage, and danced with men on tours. Justin gets it."
Strictly continues this weekend on BBC One.
