Happy Birthday, Amy Winehouse!

Since the release of her 2003 debut album 'Frank,' music fans knew they'd lucked into something special. Amy Winehouse's heartbreaking talent and signature style made her an instant icon, while her tumultuous personal life made her a constant in tabloid headlines. 2006's 'Back To Black,' her unforgettable sophomore album, won her countless awards, and her untimely death at 27 solidified her albums as classics. On the anniversary of Amy's passing, take a look through our gallery of some of Winehouse's most memorable moments.

Before she was famous, Amy Winehouse actually had a stint as a reporter—she was an entertainment journalist for the World Entertainment News Network. The "You Know I'm No Good" singer is seen here in 2004

Before Winehouse made beehives cool again, Amy was just another singer-songwriter playing local shows around London

Married for just over two years, it was clear Winehouse was quite in love with her husband, video production assistant Blake Fielder-Civil. Prior to their divorce in 2009, Amy and Blake's turbulent relationship was frequently the subject of media speculation

The multi-Grammy award winner's tremendous vocals elicited comparisons from Billie Holiday and Sarah Vaughn to Macy Gray and Lauryn Hill. But her voice was truly one-of-a-kind

But then I found out, no, it's Amy! I didn't have on my glasses."

Winehouse's last recording was the duet "Body And Soul" with Tony Bennett, featured on the jazz icon's album 'Duets II.' The pair are pictured here in 2010
