Prince Charles and Princess Diana headed on what should have been a romantic honeymoon aboard the Royal Yacht Britannia following their July 1981 wedding. But, as the world would later learn, the trip was anything but the loved-up vacation either of them had planned.

A former royal butler has revealed that the late Princess Diana’s attempts at keeping the romance alive with ex-husband Charles were ignored, insisting that the monarch "didn't have a romantic bone in his body". But he said the King had "made up for it" in his marriage to Queen Camilla.

Here's why Princess Diana's former butler claimed King Charles ignored her "romantic" gifts and gestures on Valentine's Day.

Valentine's Day is seen by some as a bit of a Hallmark holiday, and it seems the Royal Family used to think the same way—at least according to one former royal butler. Paul Burrell, who served Princess Diana from 1987 until her 1997 death, tells Marie Claire that the royals weren't big on Valentine's Day, except for the late princess.

Princess Diana "destroyed" the art supplies Prince Charles packed for the couple's 12-day honeymoon aboard the Royal Yacht Britannia in 1981, according to royal biographer Penny Junor.
