Singer’s performance will be beamed in from a London studio; her visa was rejected Thursday.

After months of speculation and suspense over whether Amy Winehouse would perform at Sunday’s Grammy Awards — where she is nominated for six awards — the Recording Academy issued a statement on Friday (February confirming that the singer will perform at the event via satellite from a London studio.

“I’m raring to go and really excited to be performing at my first Grammy Awards,” Winehouse said in a statement issued Friday. “I’d like to thank everyone for their support over the last couple of weeks. I’m really sorry I can’t be there but I appreciate that I’m being given a second chance via satellite.”

To prepare for the performance, the singer will be leaving the rehabilitation clinic where she has been a resident for two weeks. “She is feeling great, looking healthy and looking forward to doing what she does best,” the statement said, adding that she will remain under full medical supervision and her treatment will continue as normal.

Winehouse is up for six Grammys: Record of the Year, Song of the Year and Best Female Pop Vocal Performance for “Rehab,” Album of the Year and Best Pop Vocal Album for Back to Black, as well as Best New Artist.

A statement released Thursday by Winehouse’s U.K. publicity firm, the Outside Organisation, explained the circumstances of her inability to travel to the U.S. at this time. “The singer has been invited to appear at the event on Sunday after receiving an amazing six nominations for the prestigious awards. Unfortunately, her application for a visa to enter the United States of America has been rejected at this time by the American Embassy in London.”

Winehouse, who has been in a rehab facility since January, was questioned by British police on Wednesday about a video that surfaced online two weeks ago that purportedly shows the singer smoking crack cocaine. No charges have been filed against the singer, but an investigation into the video is said to be ongoing. According to the statement, “Amy has been progressing well since entering a rehabilitation clinic two weeks ago and although disappointed with the decision has accepted the ruling and will be concentrating on her recovery.”

Winehouse will be one of only a handful of new breakout talents from 2007 on a Grammys performance roster heavy with established stars such as Beyoncé, the Foo Fighters, Aretha Franklin, Tina Turner and a tribute to the Beatles.

Though fans have come to know her signature look — which includes dirty, tattered ballet slippers, a towering, often disheveled beehive hairdo and ratty, low-cut jeans — Winehouse has been photographed lately looking healthier and less gaunt than she did prior to checking into the facility, when her drawn, hollow-eyed appearance raised renewed questions about her health.

Winehouse canceled a planned U.S. tour last year after a hospitalization that was reportedly drug-related, and the Grammy performance would have been her first U.S. show in almost nine months.

“There will of course be other opportunities and she very much looks forward to visiting America in the near future,” the press release promised.
