Celebrity Gossip's

The Blonde singer Jessica Simpson is set to spice up 'X Factor'.

Jessica Simpson has been tipped to replace Louis Walsh on the judging panel and TV bosses are hoping Jessica, 26, will boost ratings.

A source told Britain's Daily Star newspaper: "They are looking for a looking for a female American judge to balance things up and Jessica is a sexy girl and will add some glamour to the show."

Paula Abdul - who sits alongside Simon Cowell on the 'American Idol' judging panel - and La Toya Jackson have also been linked to the job.

The new series of 'X Factor' will have four judges, rather than three, and BBC Radio 1 DJ Chris Moyles is hoping to grab the extra spot.

Chris, 33, has issued a come-and-get-me plea to Simon, saying: "I'm just waiting for the call. I'm definitely interested."

Simon has already revealed he would like the loudmouth DJ to join the new-look judging panel.

He said: "He is among a number of people whose names have been thrown in the ring. But nothing has been decided just yet."

'Big Brother's Little Brother' presenter Dermot O'Leary has been tipped to take over as the show's host following Kate Thorton's departure.

However, if he does agree to present the show, it will clash with the next series of 'Big Brother'.

'X Factor' auditions begin next month and the new series will air in August.
