Despite her troubled personal life, the British singer Amy Winehouse conquered five important awards at this year’s Grammies, due to her famous single “Rehab” from the “Back in Black” album.

Amy Winehouse was nominated in six categories, including all four top categories: album of the year, song of the year, record of the year and best new artist.

In the end Amy Winehouse won five awards including best new artist, best pop vocal album for Back To Black and best female pop vocal.

Unfortunately, because the US embassy in London has granted her a work visa too late, Amy Winehouse, who is currently in rehab, attended the ceremony via a satellite link.

"I can't believe I've won five awards," Winehouse said, before performing her “Rehab” hit and "You Know I'm No Good”

"To my mum and dad, for my Blake, my Blake incarcerated, and for London!" said Winehouse.

Last month, Amy Winehouse checked in the Capio Nightingale clinic in north London on January 24, after a video of her smoking crack cocaine surfaced online.

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.

“Back in Black” is the second album released by Amy Winehouse, after her 2003’s “Frank”. “Back in Black” was released in UK in October 2006 and entered at number seven on the Billboard 200 in the United States.

“I didn’t want to play the jazz thing up too much again. I was bored of complicated chord structures and needed something more direct. I’d been listening to a lot of girl-groups from the fifties and sixties. I liked the simplicity of that stuff. It just gets to the point” said Amy Winehouse about “Back in Black”
