The “rigors” of touring? No, no , no for Amy Winehouse, who has cancelled the September tour she had planned for the U.S. and Canada, in order to take care of her health.

That British singer Amy Winehouse has had a rough couple of weeks is no secret. The drinking and fast-paced lifestyle seem to have caught up with her, as reports inform us that she either is or is not in one rehabilitation facility or another.

Her publicist announced Tuesday that due to certain “health issues,” the “Rehab” singer would not be able to honor her September U.S. and Canadian tour dates.

“Due to the rigors involved in touring, Amy Winehouse has been advised to postpone her upcoming September U.S. and Canadian tour dates,” publicist Tracey Miller said in a statement.

“Plans are being made to reschedule her U.S. tour for early 2008. Until then, Amy has been ordered to rest and is working with medical professionals to address her health.”

Fans wishing refunds can get their money back at point of purchase, Miller said, specifying that, “Amy's European and U.K. tour dates in October and November remain in place.”

It was only a few days ago that fellow Brit singer Lily Allen announced she too had to cancel her September gigs in America, due to her American working visa being revoked. No MTV Video Music Awards participation for Lily, none for Amy.

The 23-year-old Amy Winehouse was scheduled to perform at the VMAs in Las Vegas, on Sept. 9, and start her string of concerts with a gig in New York on Sept. 12. It is quite probable that these plans will not be brought to fruition.

Amy has been all over the British tabloids with reports about her drinking and drug problems, fights between her parents and parent-in-law on the subject and going in and out of rehab.

She and her husband of four months, Blake Fielder-Civil, are in a “retreat,” receiving medical care for their shared substance abuse problem. Amy reportedly needed emergency treatment some weeks ago when she collapsed after ingesting a cocktail of alcohol, cocaine, Ketamine and ecstasy.

It was then that the singer apparently decided some sort of help was needed.

Blake has told BBC Radio that his wife’s situation is not as serious as it would seem from descriptions and speculations in the media.

“Me and Amy are getting better,” he told BBC Radio. “Don't worry. She's being looked after. She's going back to this retreat. She's determined to get well. It's not as bad as everyone thinks, but she's fine. She's loved and looked after.”

Amy has not hesitated in the past to talk about her drinking, calling herself a “nasty drunk” and joking about it. But the joke has worn itself out even for Amy now.
