Amy Winehouse has performed on stage in London for the second time in a week.
The star made a surprise appearance alongside her father Mitch at the grand opening of City Burlesque last night (October 7).
Mitch was performing his own show before Winehouse joined him on stage.
On Monday (October 4), the singer played a surprise set, which included new material, at the Hawley Arms in Camden.
Winehouse is currently working on songs for her forthcoming studio album.
The singer said earlier this year that the follow-up to 2006's 'Back To Black' would be released no later than January 2011.
Producer Mark Ronson said last month that he was “not sure” whether he would be producing Winehouse's next album.
