The day before the final of “Britain’s Got Talent,” Susan Boyle has been whisked away to a hideout amidst fears the singing sensation is cracking under the pressure of her sudden fame.

British tabloid The Sun reports that the Scottish singer, whose mother was born in County Donegal, Ireland, was driven away from the Wembley Plaza Hotel in London, the site where she was spotted breaking down in tears after being harangued by a tabloid reporter.

The latest in the Susan saga is that the reality TV star, 48, sweared at police officers as they interviewed her about strangers that were harassing her.

The Sun says that Boyle, whose performance of "Les Miserable’s" “I Dreamed a Dream” received millions of hits on YouTube, is alarming “Britain’s Got Talent” bosses with her erratic behavior, and they fear she may be suffering a mental breakdown.

Reportedly, the formerly reclusive singer threatened to quit the show due to the pressures of her sudden fame, but TV bosses persuaded her to stay.

In his blog, “Britain’s Got Talent” judge Piers Morgan said: “Susan is finding it very difficult to cope, and to stay calm. She has been in tears many times during the last few days, and even felt like quitting altogether and fleeing all the attention.

“She was actually going to leave the show, packed her bags to go because she couldn't see the point in going on.”

Earlier, Boyle was seen at the Wembley Plaza Hotel bar screaming “f*** off” at the TV as she watched Morgan tell “Britain’s Got Talent” contestant Shaheen Jafargholi, 12, he had given the “best singing performance so far.”

This unstable behavior is atypical for the usually cheerful Scottish woman. Morgan wrote: "Susan Boyle is a very kind, generous-hearted, lady who has had a pretty tough life. But she's always, according to people who knew her well, been a fun-loving woman who would do anything to help others.

"I'm not saying she's a saint. But I am saying that before all this fuss, Susan was generally considered to be a genuinely lovely person - albeit, one with a lively, feisty character, and a wonderfully eccentric sense of humor."

If Boyle doesn’t pull her act together, TV producers may ax her from tomorrow’s show.

Her brother John told The Sun: “Celebrities have professional people who insulate them from these stresses but she hasn't had this protection. The show's producers should have been looking after her more."
