Despite being nominated in six categories at this year’s Grammy Awards, the British singer Amy Winehouse will miss the ceremony, because the US Embassy has turned down her request for visa.

The 24-year-old soul singer received nominations for all four top categories: album of the year for "Back to Black," song of the year for “Rehab”, record of the year and best new artist.

In a press statement the Outside Organization, which represents Amy Winehouse, said the singer “although disappointed with the decision has accepted the ruling and will be concentrating on her recovery"

The singer checked in the Capio Nightingale clinic in north London on January 24, after a video of her smoking crack cocaine surfaced online.

Earlier this week, the Scotland Yard officers visited the 24-year-old at a north London clinic, where they questioned her for two hours.

This is not the first time the 24-year-old Amy Winehouse is reported to check into rehab to receive professional help for her substance abuse problem; on previous attempts though she never seemed to last long in the facility and photographs would soon surface showing her go to some local pub with her husband.

Blake Fielder-Civil, whom she married in May in Miami, Florida, is currently behind bars on charges of perverting the course of justice and assault in relation with an incident in a pub last year.

Last year in October, Amy Winehouse was arrested along with her husband Blake Fielder-Civil at a Norwegian hotel for marijuana possession. They were released after paying fines of $715 each, but both said later they had not been aware that under Norwegian law, paying the fine is equivalent to pleading guilty.

The singer is due back in court in Bergen, Norway on Feb. 29 to appeal against a fine for possessing cannabis.

The Grammy Awards will be held February 10 in Los Angeles' Staples Center; only albums released between October 1, 2006, and September 30, 2007, could be considered for this year's awards. The Grammys are determined by 12,000 music industry professionals who belong to the National Academy of Recording Arts & Sciences.
