Amy scraps US tour

Amy Winehouse has been forced to cancel an upcoming tour of North America because of her continuing health problems.

The 23-year-old singer, who yesterday quit rehab for the second time in a week, was due to play several dates in the US and Canada in September but has been told to rest.

It is not yet known whether Amy will appear at the MTV Video Music Awards early next month, where she is nominated in three categories.

"Due to the rigors involved in touring, Amy Winehouse has been advised to postpone her upcoming September US and Canadian tour dates," said Amy's spokeswoman Tracy Miller.

"Amy's European and UK tour dates in October and November remain in place. Plans are being made to reschedule her US tour for early 2008. Until then, Amy has been ordered to rest and is working with medical professionals to address her health."

Concern for the singer's health escalated two weeks ago when she was admitted to hospital for "exhaustion" amid tabloid rumours that she had suffered a drug overdose.
