Ant and Dec star in new comedy sketch Who Shot Simon Cowell?

"Wow what a party, everybody's here," says Dec. "Look that's David Walliams!"

"And Diversity," says Ant, as the camera pans to the Britain's Got Talent winners doodling over Simon's painting of Mona Lisa.

"I tell you what, Emma Bunton's looking hot tonight," says Dec.

The talent show supremo's famous friends all become suspects

As the guests arrive laden with gifts for the X Factor judge, Craig asks Louis where his present is. "I've got something for Simon, don't you worry about that," says the Irishman.

And when Stephen Mulhern spots Vicky Pattison, she shakes her head when he asks if she has a speaking part. "Never mind," he replies. "Give it a couple of years."

The birthday boy then appears at the top of the stairs and as guests start to sing Happy Birthday, the lights go off and a gunshot is fired. A dead Simon tumbles down the stairs, leaving his friends in complete shock – Sinitta in particular, who has modestly covered herself with a few leaves.

But which of Simon's pals pulled the trigger? The whodunit case puts several famous faces in the frame – those mentioned already plus Keith Lemon, Amanda Holden, Alesha Dixon, Olly Murs, Caroline Flack, Stacey Solomon, Ashleigh and Pudsey and Ant and Dec themselves.

In a plot masterminded by Broadchurch creator Chris Chibnall, can detectives Kevin Whately and Emilia Fox crack the case and determine which of Simon's celebrity friends did the deed?

Ant & Dec's Saturday Night Takeaway is on Saturday at 7pm on ITV.
