Britain’s Got Talent finalist Susan Boyle left hundreds of witnesses in shock when she lost her cool in a hotel lobby after being approached and ridiculed by two strangers, who a Britain’s Got Talent spokesman claims had been “trying to wind her up.”

The singing sensation blew her top with two four-letter outbursts while staying at the Wembley Plaza Hotel in North London this week.

“How fucking dare you! You can”t fucking talk to me like that,” Susan was overheard yelling according to spywitnesses for The British Sun.

And when one of two officers stationed at the hotel went up and asked: “Is there a problem?”

Susan raged: “Of course there’s a fucking problem.”

“You are in the public eye, you must learn to expect this sort of thing,” an officer later told her.”

One onlooker added: “It took her a long time to calm down from whatever upset her. She was breathing heavily and in a terrible rage. The pressure is obviously getting to Susan. Perhaps all the fame is too much for her.”
