Troubled singer Amy Winehouse has given her goddaughter another career boost - by performing alongside the 12-year-old at a star-studded party.

The Black to Black hitmaker was booked to appear at the Prince's Trust End of the Summer Ball in London on Thursday (25Sep08) night.

And she surprised the celebrity-packed audience by marching on stage with Dionne Bromfield, allowing the youngster to sing with her.

Earlier this year (May08) Winehouse recorded a duet with Bromfield. Their version of Alicia Keys' hit track If I Ain't Got You was later posted on video sharing website YouTube. (c) WENN
