Kylie 'helping Dannii prepare for X Factor'

Kylie Minogue is reportedly helping younger sister Dannii prepare for the upcoming series of The X Factor.

The 'Spinning Around' star is thought to have given Dannii access to her personal team of choreographers in order to make her future performers stand out from the crowd.

"[She wants] Dannii's contestants to perform to their peak during the finals. The crew will be able to give her fresh ideas and hopefully keep her ahead of the competition," an insider told This Is London.

"Kylie is a perfectionist and is giving Dannii her best pointers on how to smile, how best to bat off criticism and how to make her personality shine through."

The insider also claimed that Dannii is "feeling a little diminished" because of the alleged difference in her pay from that of fellow judge Cheryl Cole.

It is thought that Cole is being paid £750,000 more than the Australian star for the series, which will air later this year.
