London, September 18 : Amy Winehouse recently did a surprise gig at a charity fundraiser for terminally ill children.

The guests present for dinner at Rays Of Sunshine in Wrotham Park, close to her Barnet home, received a pleasant surprise when she appeared out of nowhere for a five-song set.

Meanwhile, reports have come that the troubled singer has been spending hours talking to her ex-husband Blake Fielder-Civil on the net.

"They are non-stop emailing at the moment," the Sun quoted a source as saying.

The couple had divorced earlier this year. (ANI)
