Amy Winehouse injures her hand on a wild night out.

The troubled singer was home at a 3.30am - but that was not before a turbulent few hours of water fights, punching windows, and apparently injuring her hand.

She began the night in high spirits, squirting water with a high-powered jet from her garage at fans gathered outside her Camden, north London, home shortly before 1am.

About half an hour later she fancied a trip to live music bar Stables at Camden's Proud Galleries.

She started running to the club with a mystery pal, telling photographers she was going to take them on a trip round the back streets.

She also told them - bizarrely - their mothers would like her because 'it kept it interesting'.

The 24-year-old's behavior then became more erratic over the next few hours.

Before she got to the club she slumped down outside a shop, pushing her security guard away.

The star then jumped up to slam her fist into the shop's metal security blind. She arrived home in a distraught, tearful state with a black coat over her head and red marks on her face.

Her hands were filthy and one of her fingers was blackened - perhaps a bruise from punching the grill, Mirror reports.
