Girls Aloud star Kimberley has plenty of experience of both shows, having helped out Cheryl Cole on The X Factor and now taking part in Strictly's celebrity line up.
Comparing the two show's atmosphere's from behind the scenes, Kimberley told the Daily Mirror today: “The shows are quite different. A big part of it which I have experienced is they are both voting programmes with intensity.
“But the atmosphere, the pressure and the nervous energy you feel at X Factor is totally different to Strictly.
“Strictly is like a fantasy world of happiness. Happiness, glitter and fun."
Contemplating the first elimination on Strictly this Sunday, Kimberley continued: "It will be awful when one of us has to go but it is not the be-all and end-all. With the X Factor, that is how it felt.
“I much prefer the atmosphere in and around the studio on Strictly.
“I used to go down to The X Factor and, urghh, that nervous energy. It is really tense and scary. Here, it is so warm and friendly.”
Strictly Come Dancing 2012 continues tonight on BBC One, with all of the celebs performing their second dance.
The first results show will follow on Sunday, with one celeb getting the boot and a performance from the Scissor Sisters.
