An amazing set of 11 never-before-seen pictures of Hollywood sex bomb Marilyn Monroe relaxing on the set of her classic comedy film Some Like It Hot have been revealed.
The shots are unusual because they are in colour, whereas the film was black and white.
The photographs show Marilyn chatting on set with co-star Tony Curtis in 1959 - three years before her death.

Another shows Curtis dressed in drag about to apply his own lipstick.
It was Curtis's heavy make-up which forced the film to be shot in black and white.
Originally, the production was to be in full color, but after several screen tests, it had to be changed to black and white because of a very obvious 'green tint' around the thick pan-stick required by Curtis and Lemmon when portraying Josephine and Daphne.

The pictures come from a set of slides taken on location in Florida, that are about to go on sale at an auction of showbiz memorabilia.
The sale is being organised at the Planet Hollywood Resort and Casino in Las Vegas on June 25 this year by U.S. specialist Julien's Auctions.

Boss Darren Julien said: 'In the slides Marilyn appears to relax between takes on the beach.
'She is wearing the revealing dress in which her character attempts and succeeds to seduce Curtis's character.'
The photographs were taken by a journalist on a press trip and are expected to fetch a fortune.
Other items up for sale at the two-day event include an Italian-style carved chair with green velvet upholstery used for Marilyn's last ever photo shoot.
It was for a July 1962 photo session for Life magazine by photographer Allan Grant.
The photographs were taken in Monroe's recently purchased home in the Brentwood district of Los Angeles.
Grant chose this chair and placed it below a window for the light it offered.
He asked her to choose casual clothes to wear. She chose a black sweater, capri trousers and spiked heels.
The effect of the heels is evident in a small tear in the upholstery.
As she sat on the back of the chair she also caused a small crack in the wood.
At the time of the article Monroe had just been fired from the unreleased film Something's Got To Give.
Another Marilyn lot is a pair of vintage wooden skis and ski poles with metal initials 'MM' on each ski, believed to be owned by Monroe and used in an early photo shoot around 1945.
