Queen Elizabeth II made a surprising revelation about Prince William and Kate Middleton's children.

On Sunday, the monarch revealed that 2-year old Princess Charlotte rules over her big brother 4-year-old Prince George. The admission happened when the queen asked a 10-year-old school girl, Emily Clay, if she "looked after" her 6-year-old sister.

"It's the other way around," their mom, Ellen, replied (via People). "It's like that with Charlotte and George," Queen Elizabeth II quipped.

According to the publication, the conversation happened at the Queen's Sandringham estate in Norfolk, where Emily won a bible signed by the monarch for a school religious education project. Emily's dad won the same prize back in 1990.

The Duke and Duchess of Cambridge's daughter just started her nursery school earlier this month. Middleton even shared two snaps of Princess Charlotte on her first day of school. A number who saw the photos noticed the little princess' resemblance to her great-grandmother, Queen Elizabeth II.

The two royals share the same striking eyes structure, arched eyebrows and hair color. In addition, both love the color pink, cardigans and animals.

As for Princess Charlotte's first day of school, she was reportedly "very sweet and very confident — she's always chatting away," one source said. Prince William and Middleton's daughter is also "so polite, but also fun and energetic."

"She has beautiful manners," the insider added.

In related news, Queen Elizabeth II's "Coronation" documentary just aired on Sunday. On the said show, the monarch shared the details of witnessing her father King George VI's coronation. According to the monarch, her dad requested her for a complete review of his coronation.

The queen was just 11 years old at that time. In a letter, she wrote that it was "all very, very wonderful." However, she admitted that she eventually found the ceremony boring as at the end "it was all prayers."

On her own coronation, Queen Elizabeth II revealed that her crowns were too heavy. During the interview, the monarch was reunited with the St. Edward's crown encrusted with 440 precious and semi-precious gems that she only wore once and the Imperial Crown that she has worn in most state openings of parliaments. For the queen, the headgears were too heavy that it could break one's neck.

"You can't lean down to read your speech. You have to bring [the speeches] up. Because if you did your neck would break and it would fall off," Queen Elizabeth II said. "Nothing like that is comfortable."
