Amy WinehouseAmy Winehouse is said to have been filming smoking crack-cocaine at a recent party at her home in East London.

The Sun has video footage, shot in the early hours of last Friday morning just hours before husband Blake Fielder-Civil’s remand hearing, which shows Amy snorting what is believed to be powdered ecstasy and cocaine then later inhaling on a glass pipe containing crack. She also admits to having taken “about six valium” tablets to “bring myself down”.

At one point, she is seen looking for her cat - a gift from Pete Doherty - believing that another party guest had taken it: “If I was that cat I’d leave on my own accord — I’d call a cab. It ain’t right. This ain’t Toys R Us. They took my cat.”

A source told the newspaper: “Amy is looking ill and dirty, and is so thin you wonder how much more she can take. She MUST get help.”

“Amy is locked in a nosedive towards oblivion - she is killing herself. [She’s] completely out of control.”

“Her family and her few real friends have begged her to pull herself from the brink many times. But here is proof she has pressed the self-destruct button.”

“We can only pray she will get a wake-up call when she watches the video herself and sees the terrible state she is in.”

Last August, Amy was briefly hospitalised after a drug overdose but after a few short-lived attempts to enter rehab, declared that she had no intention of undergoing treatment to beat her addiction problems.
