Amy Winehouse performed a surprise gig at the Jazz After Dark club after a 6 hour drinking session with some of her pals. That's not a gig, that's more like karaoke!

"She jumped on to the stage and started singing two new songs. Everyone was open-mouthed in amazement - she was sensational."Performing made the star peckish though: "We reopened the kitchen especially for her as she said she was starving and wanted loads of calamari and tuna mayonnaise salad."After she'd eaten, she went onto nearby Balans restaurant where she stayed until 5am, with an onlooker reporting she was "in very chatty mood and was roaring with laughter all night." However, there may have been a reason for her good mood - when she left the restaurant at 5am, she was spotted with white powder caked around her nostrils.

In other Amy news, she was nominated for 6 Grammys but at this rate she'll be lucky to be alive by the time the award show comes!
