A British tabloid newspaper published a picture on Wednesday of royal bride-to-be Sophie Rhys-Jones, showing her breast exposed.
The picture, taken 11 years ago, shows television and radio disc-jockey Chris Tarrant pulling off Sophie's bikini top.
Sophie is reported to be devastated and has said the publication has ruined her engagement.
Buckingham Palace condemned the publication and signalled possible action through the newspaper industry's watchdog, the Press Complaints Commission.
The picture published by The Sun, Britain's largest-selling tabloid, shows D-J Chris Tarrant pulling up Sophie Rhys-Jones' bikini in the back of a car.
They were on a business trip to Spain in 1988.
Sophie, then 23, was a press officer working for Tarrant.
The pictures have apparently been sold for a rumoured one hundred (TH) thousand pounds (150-thousand U-S dollars).
In another tabloid newspaper, The Daily Mail, Sophie spoke of her devastation and utter betrayal at seeing the photograph published.
She told the newspaper that the publication had ruined her engagement.
It is a far cry from this scene in January this year when the happy couple announced their engagement.
Prince Edward has condemned the publication as "a disgusting act".
According to a publicist who once employed Sophie, she told Edward about the photo more than four years ago.
The picture was sold by D-J Kara Noble, a former colleague of Tarrant's.
Tarrant on Wednesday launched an angry tirade over the publication of the photos by his former colleague.
"Kara how far down have you gone, how will you live with yourself, how will you ever face any of us at Capital, and how will you ever face Sophie again?"

Tarrant denied that there had been anything between him and Sophie.
"There was never ever the slightest hint of romance between Sophie and myself, let alone these snide insinuations, nobody dares stand up and say the fact because they know it's actionable, but they snidely insinuate there might have been an affair. There wasn't."

Miss Noble apparently gave Sophie Rhys-Jones a personal guarantee that this picture would not find its way into the public domain.
Until this morning Miss Noble worked for Capital's rival radio station Heart F-M.
The station insisted they had no involvement with selling the pictures and said they were shocked that their presenter had betrayed the trust of Sophie and then to prove the point sacked her with immediate effect.
Being in public relations, Sophie is used to dealing with the media.
Although, she certainly hadn't anticipated this sort of media attention, coming as it has only weeks before her wedding.
