Amy Winehouse allegedly punched a fan during her Glastonbury performance on
Saturday.

The troubled star lashed out when a male member of the audience apparently
groped her breasts as she stepped down from the stage to get closer to the
crowd for her final two songs.

Amy was caught on camera hitting out at the fan several times before
security separated the pair.

Glastonbury organizer Michael Eavis has defended the 'Rehab' singer's
actions, insisting she was only defending herself.

He said: "The fan deserved it. He grabbed Amy's breasts as she went past
him."

A spokesman for the Grammy award winner claims the attack was provoked when
a fan tried to pull at Amy's famous beehive hairstyle.

He said: "The 'lashing out' was when someone tried to grab her hair and she
reacted."

Police have revealed they will not pursuing the incident.

Amy - who was in hospital last week being treated for scarring of the lungs
- also commented on Jay-Z's controversial appearance on the Pyramid Stage.
She told the audience: "He has got some front to come here with tunes you
don't even remember."

The star also claimed her imprisoned husband Blake Fielder-Civil was being
released in two weeks.

She excitedly told the crowd: "My husband is out of jail in two weeks."

Elsewhere at the world famous music event, Neil Diamond treated fans to a
set full of his classic tracks including, 'I'm a Believer' - which he penned
for The Monkees - and finishing with 'Sweet Caroline'.

One surprise performance saw Lily Allen appear on stage with superstar
producer Mark Ronson, another weekend highlight included dance act Hot Chip
being joined on stage by Wiley for a rendition of his hit 'Wearing My
Rolex'.
