Prince Charles reportedly told Princess Diana his famous statement, “whatever love means,” more than once.

During the former couple’s royal engagement interview, they were asked if they were in love with each other. Princess Diana said yes, but the future King gave the shockingly cryptic response.

While speaking with Fox News, royal biographer Andrew Morton revealed that this wasn’t the first time that Prince Charles made Princess Diana feel that he didn’t really love her.

“Diana said to me that when he asked her to marry him, she said, ‘Oh yes, yes I will… I love you so much.’ And Prince Charles, even in the privacy of that moment, said, ‘Whatever love means…’ And he gave that famous television interview, ‘whatever love means,’” Morton revealed.

The author of “Diana: Her True Story” went on to say that Prince Charles’ statement made him wonder if the heir to the throne had genuine feelings for Princess Diana or if he just used her as a sacrificial lamb so that he could have children.

Despite Prince Charles’ hurtful response, Princess Diana still pushed through with their royal wedding in 1981. The mom of two thought that she would be able to come to terms with her new life as a royal and move on, but this wasn’t what happened.

“But she realized she was living this lie… seemingly the wife of Prince Charles. And yet you got Prince Charles, who was effectively with another man’s wife at Highgrove, their country estate, while she languished alone at Kensington Palace,” Morton said.

During their honeymoon, Princess Diana also found a bracelet that Prince Charles was supposed to give to Camilla Parker Bowles. She also saw photos of the Duchess of Cornwall in her husband’s diary.

According to Morton, Princess Diana was suspicious of Prince Charles’ relationship with Camilla from the get-go and no one could blame her for feeling that way. Especially since her gut feeling was right.
