Alesha Dixon is asked to fire staples at a 'Britain's Got Talent' hopeful this weekend.

The glamorous judge is enlisted by magician Ryan Tricks to be a part of his act in a try-out that will air on spin-off show 'Britain's Got More Talent'.

Handing Alesha a staple gun, Ryan tells her: "Have you heard of Russian roulette? It wouldn't be clever to use real guns so I use staple guns."

Ryan loads the gun with staples and tries to use his mind to influence Alesha with which ones to pick.

The nervous judge then pulls the trigger against his hand, cheek and neck.

Elsewhere on the show, Simon Cowell tries to claim his car counts as "public transport" because he lets other people into the vehicle.

Asked by host Stephen Mulhern when he last used public transport, Simon says: "Probably yesterday!"

His fellow judge David Walliams butts in to say: "You liar! You've got a Rolls Royce!, prompting Simon to retort: "But other people can get in it."

When David says "I had a ride in it for 30 seconds", Simon quips: "That makes it public transport!"

'Britain's Got More Talent' airs on Saturday 20 April on ITV2 at 8.30pm.
