London, Dec 17 : Rumours are rife that Aussie singer Dannii Minogue, 37, may be sacked and replaced by English singer Robbie Williams as an X Factor judge.

Simon Cowell, one of the show's bosses, is said to be looking forward to forming his dream team with Cheryl Cole, Louis Walsh, and Williams so that the panel gets more pop star quality.

"It looks like Simon has decided on his dream line-up and is determined that's what he will get," the Daily Star quoted a source as saying.

"He's used to getting his own way so he'll be going all out to get Cheryl. Getting Robbie would also be an amazing coup - he's a megastar," the source added.

Minogue, however, has denied that she is to be axed from the show, insisting that the producers want her there.

"The producers and Simon tell me I am returning, so that's all I believe. So unless I hear differently then I'll be back," Minogue said.

Backing her claim is a spokesperson for the show, who says that no decision has been made as yet.

"No decisions have been made about contracts and no decisions will be made until next year," the spokesperson said.

"It's all speculation," the person added. (ANI)
