Randy Jackson and Ryan Seacrest Set Up Simon Cowell to Get Punk'd  5/12/05

British music mogul Simon Cowell has vowed to take revenge on Ashton Kutcher, after falling victim to one of his pranks on hit US TV show Punk'd.

Cowell has joined a long list of celebrities - including Halle Berry, Ashlee Simpson and Justin Timberlake - to be fooled on the show, after his American Idol colleagues Ryan Seacrest and Randy Jackson set him up for a fake car-jacking.

Cowell was horrified when he learned his prized $320,000 Rolls-Royce Phantom was "stolen" from outside a fake house party, causing another vehicle to crash into the house.

A source says, "Simon fell for it 100 per cent. He is fuming and plotting his revenge."

It has yet to be announced when the episode will air.
