Amy Winehouse will still sing at the Grammy Awards this weekend, despite her U.S. visa ban.

The troubled singer will be performing via satellite from London at the ceremony, where she has been nominated for six of the prestigious music industry awards.

The star's visa refusal was a blow to Winehouse, who is currently being treated in rehab for drug addiction at the private Edward house clinic in north-west London.

Her application for a visa to enter the U.S. was rejected by the American Embassy in London, following widespread publicity over a 19-minute video said to be of the 24-year-old taking a potentially lethal cocktail of crack cocaine, Ecstasy and Valium.

Following the ruling, Winehouse said: "I'm raring to go and really excited to be performing at my first Grammy Awards. 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."

Her spokesman added: "To prepare for the performance, Amy will be leaving the rehabilitation clinic today where she has been a resident for two weeks.

"She is feeling great, looking healthy and looking forward to doing what she does best.

"She will remain under full medical supervision and her treatment will continue as normal."

Only the rap star Kanye West received more Grammy nominations - the music industry's answer to the Oscars - than Winehouse.

In December, she was arrested over an alleged £200,000 plot to fix her husband Blake Fielder-Civil's assault trial. It is understood she was questioned.

Fielder-Civil, 25, is on remand in Pentonville prison, North London, on charges of attempting to pervert the course of justice.
