Dionne Bromfield has shown absolute professionalism and maturity during the two weeks since her godmother Amy Winehosue passed away. But it all got too much for the 15-year-old singer when she sang a cover of Amy’s Love Is A Losing Game at the Big Chill festival in Herefordshire last night.

The Mama Said singer broke down in tears as she sang the hit song. Witnesses say she was barely able to sing the last few words but the crowd kept her spirits up by cheering.

With tears in her eyes, Dionne told the crowd

She was an amazing singer. She was not only my godmother, but she was my mentor and my boss as well.

Amy Winehouse was found dead at her home in Camden, north London, on 23 July. The cause of her death is still unknown.
