Paula AbdulPaula AbdulPaula Abdul is once again fighting off rumours of an affair with an American Idol contestant.

The latest threat comes in the form of a stateside documentary, which is thought to contain fresh allegations of Paula's supposed affair with 22-year-old contestant, Corey Clark.

Titled Fallen Idol, the report claims to offer a behind-the-scenes look at the hit show, including evidence linking Paula to Corey.

Paula's lawyers are already on the case and have threatened to sue if the programme, due to be aired tomorrow night, is shown.

A statement, released by Paula's people, labels Corey a "liar and an opportunist".

Corey, who claims the affair took place while he was a contestant on the show in 2003, has promised to reveal all in a 'warts and all' type book.

If the reports are found to be true, Paula is likely to be sacked and will be the first judge to be booted off the show.
