The never-before-seen footage shows the late actress smoking a cannabis joint - a cigarette lace with the drug - while relaxing at a friend`s home in New Jersey 50 years ago.

The silent film was shot by an unnamed filmmaker friend of Marilyn - who died tragically in 1962, aged just 36 - who confirmed the beauty was inhaling the drug.

The filmmaker said: "I got the marijuana. It was mine. It was just passed around. It was not a party. It was just a get-together. You know, come over and hang out."

Blonde Marilyn can reportedly be seen taking a puff on the cigarette, sniffing her armpit and giggling.

The video spent many years hidden in a loft before New York collector Keya Morgan bought it for $275,000.

Describing the footage, Keya said: "This is the late 50s so she is already very famous, but this is a personal side of her we`ve never seen before. People have never seen her in such a relaxed pose."

The collector - who is currently making a documentary about the tragic actress - plans to put the clip up for sale on auction website eBay later this week.
