Simon Cowell was nearly struck by a knife at the 'Britain's Got Talent' auditions over the weekend.

The reality TV judge was so impressed by an 11-year-old knife-thrower at the Birmingham auditions for the new series, he decided to join the youngster on stage for a demonstration.

However, the 54-year-old music mogul got more than he bargained for when he was nearly hit by one of the metal utensils.

Simon, who was propped in front of a wooden board, was unharmed when the first knife thrown by the boy lodged itself into the board. But the second knife got a little too close to the 'BGT' judge before falling to the floor.

Deciding to return to his seat after the near-miss, fellow judge David Walliams wailed: "You nearly killed Simon!"

The comic then quipped: "How much would I have to pay you to throw the knife a little bit nearer?"

The weekend's auditions also marked the first time one of the judges hit the Golden Buzzer - a new feature which automatically puts the contestant on stage through to the live shows.

Each judge can press the buzzer once during the auditions stage and Amanda Holden became the first to invoke her right after being impressed by a salsa dancing act.
