Amy Winehouse has been accused of punching a fan outside her home in North London.

The alleged incident is to have taken place last weekend – just seven days after the singer lashed out at fans during her appearance at the Glastonbury Festival.

A report in today's Sun newspaper says Winehouse was provoked in the latest incident after the fan touched her body.

“She just lashed out and clumped him. He laughed it off,” an unnamed source told the newspaper.

As previously reported, Winehouse performed to huge crowds in Madrid on Friday at the Rock in Rio Festival.
