AMY Winehouse faces ruin after being caught on camera revelling in SEX in a public place, out of her head in a CRACK den and singing an astonishing RACIST chant.

Our bombshell revelations— based on sickening video footage and over 100 shocking still photos—will stun fans and threaten to torpedo troubled Amy's rock career.

The damning scenes were filmed by her husband Blake Fielder-Civil, who is in prison facing trial for GBH and conspiracy to pervert the course of justice.

We were handed the explosive material by a former friend determined to show the world just what power Blake wields in manipulating the vulnerable young star.

In a sequence shot around May 2007—weeks after the couple eloped to wed in Miami—they are in a dingy crack den with Delboy-style bamboo patterned wallpaper.

Amy, 24, and a pal called Sarah giggle as they sing a string of racist lines set to the tune of kiddies' favourite ‘Heads, Shoulders, Knees and Toes'.

Blake pretends NOT to record the unfolding events and eggs them on, saying: "Can we have a singsong of it?"

Sarah is at first reluctant but soon warms to the action as Amy enthusiastically sings:

"Blacks, Pakis, Gooks and Nips, Gooks and Nips!

"And deaf and dumb and blind and gay!"

She repeats the first line over again and on the word "Nips" Amy pulls her eyes into slits then pushes her boobs up in a gesture to her nipples.

The girls' efforts are greeted warmly by Blake, who pledges: "Well done. I promise I wasn't recording it."
