The pop songstress is rumoured to be a judge on the next series of the reality TV show. Although nothing is official, she says people started saying "well done" as soon as the rumours emerged.

"I am in hysterics," she told the Daily Mirror. "I’ve spoken to them and it would be great. Nothing has been signed - but I’ve had loads of congratulations."

It has been reported that Kylie’s sister will join new host Dermot O’Leary and a new male judge, along with Simon Cowell and Sharon Osbourne.

But an X Factor spokeswoman refused to confirm whether Dannii, 35, had been appointed as a judge, saying: "It’s just speculation at this time."

The spokeswoman said the two new judges would be announced by the end of this week.

The rumours come after Louis Walsh and Kate Thornton were kicked off the show, which is due to return in August.

Has Dannii got the X Factor? - April 4 2007
Dannii Minogue might be set to glam up X Factor, as it’s rumoured she’s been signed up as a judge on the show.

Kylie’s pop star sister will apparently join new host Dermot O’Leary and a new male judge, along with Simon Cowell and Sharon Osbourne, when the show returns, the Daily Star reports.

But an X Factor spokeswoman refused to confirm whether Dannii, 35, had been appointed as a judge, saying: "It’s just speculation at this time. We will announce the two new judges by the end of next week."

The paper claims Dannii was picked by talent show boss Simon after she appeared as a judge on another of his shows, Australia’s Got Talent.

An insider said: "Dannii is a great name for us. She’s an established pop star and she’s got lots of connections in the business - not least of which is her sister, Kylie."

Dannii, who had chart hits with Love And Kisses and This Is It, is also said to be a huge fan of the ITV show.

"The auditions are my favourite. The more they can’t sing, the funnier it is. I know that sounds terrible, but we all love a bit of car crash reality TV," she’s quoted as saying.

The rumours come after Louis Walsh and Kate Thornton were kicked off the show, which is due to return in August.
