The two had appeared in a film together called Let’s Make Love.Marilyn was married to the playwright Arthur Miller at the time.

The world exclusive images of the tragic actress were auctioned in Hollywood in November last year from the estate of Frieda Hull and sold for just $2,240.Hull, dubbed them the ‘pregnant slides’ a reference to a shocking secret the siren kept right up until her death.

Tony told Daily Mail

"Frieda was very proud of those slides and she was very proud to keep them a secret until the day she died.But she told me the story behind them, that Marilyn got pregnant by Yves Montand.”
