A shocking video where actress Angelina Jolie is seen in shockingly thin shape pacing around a filthy New York City apartment has emerged online.

The 16-minute clip, which is believed to have been shot at the Ansonia Hotel building in New York City in 1999, was posted online by US tabloid the National Enquirer, Tuesday night, reports contactmusic.com.

It shows Jolie looking extremely thin, with messy, dyed blonde hair, walking around an untidy room covered in soda cans and piles of clothes, and talking on the phone. She is heard discussing family issues with a caller said to be her actor father Jon Voight.

The man who shot the footage, a former drug dealer named Franklin Meyer, alleges the actress was one of his clients and the video was taken with her consent. Jolie has been open about her past battles with drugs before she turned her life around and became a Hollywood superstar.

Franklin Meyer revealed that she only sniffed but never smoked.

In a video posted by Radar Online, the 68-year-old drug dealer said that during their deals, he only sold her cocaine and heroin that too in small quantities.

Meyer, who claims that their bond was "more than a dealer-client relationship", added that the scandalous video of Brad Pitt's fiance was taken during one of his visits to the actress's place in late 1990s to deliver something.

"It was just one time when I went up there to deliver something and we were hanging out," Franklin says of the 16-minute never-before-seen footage of Jolie he took, with her permission.

"We sorta had a friendship, it wasn't just a dealer-client kind of thing. We liked each other's company and we'd talk quite a bit."

And despite Jolie appearing to have marks and bruises all over her arms, Franklin says he never saw Brad Pitt's future wife shoot up with needles.

"She never bought large quantities. She just bought smallish amounts," he said.

"Keep in mind she just sniffed, as far as I know she didn't smoke or shoot or do anything like that."
