Miley Cyrus is making 'X Factor' bosses nervous ahead of her performance on the show tomorrow (17.11.13).
Miley has reportedly been told to tone down her act for the family-friendly show after her recent controversial twerking and joint smoking on stage.
The Daily Star reports "Miley seems to be on a mission to be as controversial as possible so everyone's a bit nervous. She's been told to tone it down for The X Factor. That said, we're not stupid."
Although big bosses don't want the performance to result in complaints, head judge Gary thinks 20-year-old should include her controversial rump-shaking move.
Earlier this week he said: "It's music - she's a young girl. If that's the way she wants to express herself, fair enough. It's a tricky one because I remember Madonna when she brought her 'Sex' book out and everyone was going crazy. That seemed more shocking.
"But, you know, there's an off button. I always say, if you don't want to watch it, turn it off."
He added: "These singers are young, sexy girls - of course they are going to express themselves like that. But I don't let my kids watch it.
"I probably wouldn't let them watch anything like that, it's too sexual for them."
