Amy Winehouse has apparently reduced a pub crowd to tears, for all the right reasons, during an impromptu gig.

According to the Daily Mirror, the Back to Black singer got up on stage during a charity gig at her local, the Hawley Arms in Camden, and gave a pitch perfect performance of Tears Dry On Their Own.

The 27-year-old is then said to have carried on singing whilst Sadie Frost's ex Kristian Marr on guitar.

Meanwhile Amy claims she has been drug-free for three years.

Speaking to Glamour magazine, the troubled star said: "I'm much healthier now. I used to use drugs and I haven't used drugs in almost three years. It's not a hard thing."

She also revealed she is thinking about having children:

"I'm of the age when you start thinking about it - not seriously - but you start thinking about having kids. Although I'm not going to be getting pregnant in the next nine months."
