Now, her career can begin...

Almost a week after she was upset in the Britain's Got Talent finals, Susan Boyle has left the mental health care facility into which she was checked last Sunday.

Sources have confirmed that Boyle is no longer a patient at the London Priory Hospital. She'll continue to rest this weekend, though it's unclear if the singer will immediately return to her home in Blackburn, Scotland.

Next week, Boyle will meet with 19 Management, Simon Cowell and Sony BMG to discuss her recording contract and impending album. Score!

"Susan wants to get on with it now," says a source. "She's not quitting - those rumors are rubbish.
