British singing sensation Amy Winehouse has won five Grammy awards,

British singing sensation Amy Winehouse has won five Grammy awards, including record and song of the year for her autobiographical hit Rehab.

The jazz star, whose personal life is in turmoil, also picked up best new artist, best pop vocal album for Back To Black and best female pop vocal.

Visa problems prevented the 24-year-old from attending the ceremony in Los Angeles in person, but she performed You Know I'm No Good and Rehab in front of a small audience in a London studio which were beamed to the US via satellite.

After a standing ovation at the Grammys, she said: "Thank you very much, it's an honour to be here. Thank you very, very much."

Winehouse looked stunned as she won record of the year and stared straight ahead for several seconds as the television feed cut to her.

Her performance was a rarity given the star's recent health problems. She ended up cancelling her UK tour after several shambolic performances, citing husband Blake Fielder-Civil - who is being held in custody - as the reason she could not go on.

But after winning the five awards, she hugged several people, including her mother Janis, as the crowd chanted: "Amy, Amy, Amy." The singer put her arm around her mother and added: "To my mum and dad. To my Blake, my Blake incarcerated."

Referring to this weekend's blaze which ravaged Camden Market and celebrity hangout The Hawley Arms pub - a favourite of the troubled singer - she went on: "And for London, this is for London, because Camden Town is burning down."

Although she was absent from the ceremony, she certainly wasn't without her supporters in the States.

Bat Out Of Hell singer Meatloaf said the visa delay was a joke: "I thought it was fairly silly that they wouldn't give her a visa to come over, I didn't quite get that. I mean she didn't shoot people. I would understand a serial killer not being allowed in - it's a bit strange."
