Troubled singer Amy Winehouse has apologised after being caught in yet another shameful video which shows her surrounded by evidence of drugs and singing racist chants.

The home video footage was filmed by husband Blake Fielder-Civil, who is currently in prison facing trial for GBH and conspiracy to pervert the course of justice.

Amy's latest shocking video comes just days after Sir Ian Blair called for celebrities caught taking drugs on camera to be put on trial.

The Metropolitan Police Commissioner said jurors should be given the chance to decide if illegal substances have been taken, reasoning that: 'a sensible jury would not expect people to be snorting talcum powder'.

The video, which was reportedly handed to the News of a World by a friend, shows Amy, 24, and another woman singing racist football chants to the tune of children's song  'Heads, Shoulders, Knees and Toes'.

However they have replaced the words with 'Blacks, pakis, gooks and nips' followed by: 'And deaf and dumb and blind and gay'.

A coffee table can be seen in the background displaying six cigarette lighters and a substance which looks like heroin on a foil.

In another section Blake, 26, asks Amy to perform a sex act on him in the public stairwell of a hotel. This is followed by a confused sequence showing shots of the steps and carpet.

Further footage shows Amy asleep while a friend Eddie discusses which drugs they have taken. He tells Blake  'A little bit of E, a little bit of C and a few beers, watched telly, smoked crack.'

Several photos of Amy have also been released including pictures of her surrounded with a pipe made from a bottle, and silver foil which appear to be drug taking paraphernalia.
