Winehouse had reconciled with her father since then, but that did not seem to help her to stay sober.
Mitch Winehouse, an aspiring singer himself, said he knew his daughter's career and the publicity surrounding her personal life helped his chances at a music career.
"It [the relationship between father and daughter] was complicated," said Ian Drew, senior music editor of US Weekly magazine. "She loved her father, but he also fed off of her."
"He couldn't rein her in as much as he loved her,"said Drew.
In January 2008, British newspaper The Sun posted a video of Winehouse allegedly smoking crack cocaine and talking about taking ecstacy and valium. The video was later passed on to investigators, who arrested and questioned Winehouse but did not file charges against her.
Later that month, Winehouse finally checked into rehab, but left the treatment program two weeks later. In February 2008, she won five Grammys, including Best New Artist and Album of the Year.
In addition to her health woes, Winehouse often found herself embroiled in legal dramas.
In October 2007, Winehouse and her husband, Blake Fielder-Civil, were arrested in Norway for possession of marijuana. They were later released and fined.
When Fielder-Civil was accused of assaulting a pub landlord in June 2007, Winehouse was accused of trying to interfere in his trial. He was eventually sentenced to a 27 months in prison on charges stemming from the assault.
But Winehouse's health and legal problems didn't hinder her popularity. In May, The Sunday Times newspaper's annual Rich List estimated her wealth at $20 million. According to the same paper, "Back to Black" had sold nine million copies worldwide as of July 2008.
Winehouse is listed as a performer on Tony Bennett's upcoming album "Duets 2," which is due out in September. She and Bennett sang the jazz standard "Body and Soul."
"Amy Winehouse was an artist of immense proportions and I am deeply saddened to learn of her tragic passing," Bennett said in a statement today.
"She was an extraordinary musician with a rare intuition as a vocalist and I am truly devastated that her exceptional talent has come to such an early end," he said. "She was a lovely and intelligent person and when we recorded together she gave a soulful and extraordinary performance. I was honored to have the opportunity to sing with her."
He said he had hoped that she would "overcome the issues she was battling."
Winehouse's death follows suit with a number of rock singers who died at age 27, including Jimi Hendrix, Janis Joplin, Jim Morrison and Kurt Cobain.
