Victoria Beckham will join Idol as a guest judge

In the wake of Paula Abdul's surprise exit from American Idol, Simon Cowell has called on a old friend to join him on the judging panel - one Mrs Victoria Beckham.

The former Spice Girl has so far agreed to make one guest appearance on the show for a rumoured £155,000.

Her spokesperson told Mail Online: Yes Victoria will be making a "one off" appearance as a guest judge.'

The singing contest is still the highest-rating programme in the U.S. drawing an average of 26.3 million viewers per episode, making the role an impressive coup for the former Spice Girl.

She has been steadily building her profile in the since her move to the U.S. in 2007 but has yet to really make her big break.

Her appointment may come as a surprise to some, considering that even by her own admission she is not a particularly good singer.

'I worked hard at it,' she recently admitted, but: 'I was never going to be the best singer or dancer.'

A source says Posh is not interested to take over Paula's role permanently.

She is still determined to concentrate on her fashion projects, according to the insider, and is currently working on the upcoming launch of her new collection at New York fashion week in September.

Abdul announced just yesterday that she was leaving the show after eight years.

'With sadness in my heart, I've decided not to return to Idol,' she posted on her Twitter page last night.

While the TV talent show judge did not expand on her reasons for leaving the programme, she had been lobbying for a significant pay raise during negotiations for a new contract in recent months.

She was said to be particularly annoyed after hearing reports host Ryan Seacrest had secured a $45 million, 3-year deal, while she was being offered a rumoured $2 to $3million a year.
