Prince Charles reportedly sent a secret message to Camilla Parker Bowles during his engagement interview with Princess Diana.

During their interview, Prince Charles and Princess Diana were asked if they were in love with each other and the engaged couple gave very different answers. Princess Diana instinctively said “of course,” but Prince Charles replied, “whatever love means.”

In the documentary “Princes of the Palace,” royal biographer Penny Junor said that this statement hurt Princess Diana’s feelings.

Author Chris Hutchins added, “It must have hurt her enormously when he said that because what would our wives have said if we’d said on the day of our engagement publicly ‘whatever love means.’”

Biographer Robert Lacey claimed that Prince Charles’ answer was actually his message for Bowles. It is believed that Prince Charles always loved Bowles but couldn’t marry him because she was no longer a virgin.

“Poor Camilla’s problem was Catch 22, when she met Prince Charles they fell in love, they went to bed together. That sort of automatically ruled her out as a future Queen,” Lacey said (via Express).

But despite Princess Diana’s hurt feelings, she still decided to marry Prince Charles in July 1981. A year earlier, the Princess of Wales also saw incriminating evidence confirming Prince Charles and Bowles’ affair.

While in one of Prince Charles’ employees’ study, Princess Diana saw a beautiful bracelet with the letters “GF” engraved on it. The mom of two immediately knew that the bracelet was intended as a gift for Bowles.

Jessica Jayne, the author of “The Duchess of Cornwall: Camilla’s Story and Secrets,” said that GF stands for Gladys and Fred, Prince Charles and Bowles’ pet name for each other. The monikers were taken from the future King’s favorite entertainment “Goon Show.”

And during Prince Charles and Princess Diana’s honeymoon, the latter discovered two photos of Bowles tucked in her husband’s diary. The cufflinks that Prince Charles wore to a party that they attended also featured two interlinked “C’s” that signify Charles and Camilla.
