Amy Whitehouse loses the plot on a rampage

But this weekend the 24-year-old went on the rampage in Camden, London, and ended up getting into some fisticuffs with a storefront security fence.

London's Daily Mail reports that the troubled star began her night at around 1am by playfully soaking fans outside her apartment with a high-pressure hose from her garage.

Then she began a crazed sprint through the backstreets, laughing with paps and challenging them to keep up with her.

But her high spirits quickly crashed, and Amy sat down in a storefront doorway -- before savagely attacking its metal security grille.
