Amy Winehouse's unconventional lifestyle, it seems, has caught up with her. The British pop star has been forced to pull the plug on her schedule for the rest of 2007, due to unspecified illness.

Winehouse has "cancelled all remaining live and promotional appearances for the remainder of the year on the instruction of her doctor," according to a statement issued Tuesday by her record company, Universal Music.

The statement continues, "The rigours involved in touring and the intense emotional strain that Amy has been under in recent weeks have taken their toll."

Winehouse, Universal says, "has been ordered to take complete rest and deal with her health issues."

The company also quoted the artist as saying, "I can't give it my all onstage without my Blake. I'm so sorry but I don't want to do the shows half-heartedly; I love singing. My husband is everything to me and without him it's just not the same."

Her husband, Blake Fielder-Civil, is currently being held on remand, accused of inflicting grievous bodily harm in an incident in June 2006.

Winehouse, who has a reputation for heavy drinking and hard partying, pulled a stretch of European concerts in August after being admitted to the hospital suffering from an alleged drugs overdose. At the time, her label described the ailment as "severe exhaustion."

In recent weeks, the crossover jazz-pop artist has come under intensifying scrutiny from the British press over a string of wobbly performances, and her increasingly dishevelled appearance.

Poor reviews, however, have not curtailed sales of Winehouse's records. Her debut "Frank" is certified double-platinum in Britain and currently stands at No. 43 after 68 weeks on the Official U.K. Chart. Her smash sophomore set "Back To Black" is at No. 12 after 56 weeks on the chart, and is certified five-times platinum. A deluxe edition of "Back To Black" is at No. 37.
