The disastrous relationship between Prince Charles and Princess Diana has gone down in modern history as one of the saddest love stories.

Prince Charles and Princess Diana were the ‘IT’ royal pair and people across the globe watched their budding marriage only for it to end up in a bitter divorce and Diana’s eventual death.

But there were already signs of Prince Charles and Diana Spencer’s marriage life was doomed. In an unearthed transcript from ITN’s exclusive interview in 1981.

After the engagement announcement of the royal pair, ITN’s royal correspondent Anthony Carthew was given the privilege to get an exclusive dialogue with Charles and Diana.

Several topics were discussed during the televised meeting but one important question was snipped up from the national broadcast.

According to royal insiders, Carthew asked the pair if they were ‘in love.’ Princess Diana was said to be quick in answering, replying to Carthew’s question with ‘of course.’

On the other hand, Prince Charles let go of a cryptic statement, which could have been the first sign of an ominous relationship.

Transcripts revealed that the Prince of Wales answered Carthew's question with this: ‘Whatever ‘in love’ means.’

This portion of the interview was left out when it was broadcasted across the globe. Instead, it was kept mum as it did not come in line with the perfect couple the Palace advisors wanted to project.

New Zealand Herald reports that royal experts believe that these four words uttered by Prince Charles locked the fate of the couple's relationship.

The couple’s dating history was very short as they were only rumored to have met each other sixteen times before getting engaged.

There were also rumored to be several factors behind the marriage of Prince Charles and Diana. The daughter of a Viscount, Diana Spencer, was very much the perfect royal wife for the future King of England.

Prince Philip was said to have given Prince Charles an ultimatum on his relationship with Diana, encouraging the Prince to decide or let go of the lovely aristocrat.

Not even 10 years after their nuptials, the royal couple underwent a very publicized divorce after both parties were accused of having affairs.

Prince Charles infamously married Camilla Parker-Bowles in 2005, the woman who UK citizens blame for Charles and Diana’s failed marriage.

Princess Diana passed away in a freak car accident in Paris in 1996.
