Susan Boyle has been distraught because of her financial situation as her management team only give her $450 to live on a week.

The “Britain’s Got Talent” winner turned international success story has been banned from having a credit card or withdrawing any extra money out of the bank. According to the New of the World this lack of cash has left her unable to furnish her new home.

“Her millions are ring-fenced but Susan has no concept of money,” said Gerry, Susan’s brother. “She was extremely distressed. She lives in fear of losing everything and returning to her old life before she made it big.

"So she's still stuck in the small council house where we all grew up. She should be able to walk into a bank anywhere and say she wants £50,000 cash. That may not be advisable, but it would be her choice because it's her money.

"Susan is baffled about money. All she wants to do is sing. So we asked the questions that should have been asked a while ago. 'Why doesn't she even have a credit card? Why does she feel she doesn't have control over her finances?'

"Susan isn't financially astute but she is worried about her situation. She looks very distraught at the moment. And we've got worries about her safety, too. She visits the local Tesco most days all on her own. So we raised concerns about security with her management.

"Susan doesn't look as if she's a successful international chart star. She's lonely and downtrodden. And she's got this paranoia that she's going to go back to square one, back to where she was before Britain's Got Talent."

A spokeswoman for Simon Cowell's company SyCo said: "Finances are handled directly between an artist and their management, therefore we do not comment on such matters."
