Fritha, 11, from Lichfield in Staffordshire joined in with the dancing and said: "Her outfit's okay. It's just Kylie."
And Daniel, 11, from Wellingborough, thought it was "absolutely fine".
There were only a couple of kids who didn't agree. Holly, 10, from London was one of them. She said she liked the waxwork and the dancers, but thought Kylie should be in a different pose and dress.
The Fever exhibit is on until 8 September. After that Kylie will join the rest of the waxworks on display in the main halls.
