Queen Elizabeth II love a certain soup.

Chef Mark Flanagan revealed in a preview of the upcoming ITV documentary "Queen of the World" that Her Majesty has asked for callaloo soup to be served more often. She was introduced to the dish when a group from the Caribbean cooked for the Buckingham Palace's kitchens.

The callaloo recipe includes chili peppers. Jared Forbes revealed that from the Bahamas, they chose the recipe to give "a little idea of what we eat at home."

"A number of the Caribbean dishes were particularly well received," Flanagan said (via Express). "The callaloo soup was an absolute sensation. I had email after email telling me that it must now feature more regularly."

In another clip of the documentary, the Queen was captured delivering a speech for the 2017 Christmas message when a bird interrupted her. The monarch was in the middle of reading the speech when a member of the staff asked her to redo it from the top.

"From the very start," the team member requested.

"You want the whole thing again?" the Queen asked again.

"If possible," the member of the staff said.

Queen Elizabeth II, who is fond of animals including horses and dogs, just giggled.

"Queen of the World" will air on Tuesday at 9:15 p.m. EDT on ITV.

In related news, Queen Elizabeth II and Princess Diana reportedly had a complicated relationship. The late Princess of Wales tried to ask for the monarch's advice when her marriage with Prince Charles was at its lowest, but Her Majesty was less than sympathetic. Queen Elizabeth II just told Princess Diana that her marriage was "loveless."

On the other hand, Princess Diana also challenged the monarchy. She had broken multiple royal protocols by choosing her own engagement ring and refusing to say that she would "obey" the Prince of Wales during their wedding vows.

Prince Charles' second wife also didn't endear herself to Queen Elizabeth II initially. The Queen apparently "actively disapproved" of Camilla Parker Bowles for Prince Charles. Tom Bower claimed in his book "Rebel Prince: The Power, Passion and Defiance of Prince Charles" that the monarch was not supportive of Prince Charles and Camilla's romance, so there was a cold war among the members of the royal family.

The Queen reportedly didn't want to see Camilla in any royal function. But she eventually accepted the Duchess of Cornwall. Prince Charles and Camilla got married on April 9, 2005.
