British singing sensation Amy Winehouse has been honoured with five Grammy awards despite missing the star-studded event.The jazz star won record and song of the year for her autobiographical hit Rehab and picked up best new artist, best pop vocal album for Back To Black and best female pop vocal.But the 24-year-old was kept from winning in all of her nominated categories by Herbie Hancock who was the surprise winner of album of the year for River: The Joni Letters.Winehouse was unable to attend the glamorous LA ceremony in person because of visa problems, but her performance of You Know I'm No Good and Rehab in front of a small audience at a London studio was included in the show via satellite.After a standing ovation at the Grammys, Winehouse 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."Other big winners of the night included Kanye West, who took four Grammys for best rap album of the year for Graduation, best rap solo performance for Stronger, best rap song for Good Life and best rap performance by a duo or group for his collaboration with Common on Southside.West paid tribute to his mother Donda West, who died last year after complications from plastic surgery, by performing a special version of his 2005 song Hey Mama.© Independent Television News Limited 2008.
