Amy Winehouse's goddaughter Dionne Bromfield performed a moving set at the Big Chill music festival in England Saturday, closing with a cover of the Winehouse hit, Love Is A Losing Game.

The 15-year-old was barely able to get through the song, telling her audience Amy was "not only my godmother, but she was my mentor and my boss as well."

Amy Winehouse's goddaughter, singer Dionne Bromfield has been getting support from thousands of the tragic performer's mourning fans via Twitter.

Winehouse - who was mentoring the 15-year-old's career - appeared live on stage with Bromfield just three days before her shocking death at her Camden home.

And the aspiring singer - who now has more than 43,000 people following her Twitter page - is grateful for the condolences as she tries to get over the loss of her musical mentor.

Amy Winehouse may have passed away, but new music from the tragic performer could now be released posthumously.

As her heartbroken father Mitch Winehouse went public by thanking fans for supporting the family after her sudden death over the weekend, it emerged that new material could soon become available.

The Rehab singer has sporadically been working with producers and friends Salaam Remi and Mark Ronson on her third album over the past two years.

Looking surprisingly happy and healthy, Amy Winehouse made her final-ever public appearance just three days before her tragic death.

The 27-year-old singer, found dead in her London home Saturday, appeared on stage alongside her goddaughter and protege Dionne Bromfield during her gig Wednesday night at a London nightclub.

Wearing skinny jeans and a black polo shirt Amy chewed gum and smiled throughout the performance before hugging Bromfield and addressing the screaming crowd.

Winehouse had not been on stage since her disastrous appearance in Belgrade last month. That show was cut short by a booing audience, leading to the cancellation of her planned European comeback tour.
