Kate Middleton, Prince William and Queen Elizabeth II unveiled a special war memorial Thursday in London. During the visit, the Duchess of Cambridge spoke to the wife of a Royal Marine commando about her kids — Prince George and Princess Charlotte.

After the conversation, Samantha Burge told reporters that Middleton thinks Princess Charlotte is the one in charge of the royal family. Middleton also spoke about the closeness between her two children.

“[Kate] said that Charlotte is growing up really fast. She is the one in charge,” Burge said, according to People magazine, adding: “We have both got two-year-olds and they are ruling the roost. It was a bit of a mummy chat.”

“[Kate said] they are both becoming really good friends, George and Charlotte,” Burge, who is a mother to daughters Isabella, 4, and Amelia, 22 months — similar in age to the royal children, George and Charlotte, said.

Recently, Middleton has been opening up about the royal children as she mentioned about Prince George's hobbies during Pancake Day.

When inquired about the young Prince’s whereabouts during Middleton's visit to the Ronald McDonald House in London, the duchess responded, “George? I should have brought him. He’s at his Montessori nursery today making pancakes.”

Kensington Palace announced in January that Prince William and Middleton are relocating their family to the palace from Anmer Hall in Norfolk.

“Their Royal Highnesses love their time in Norfolk and it will continue to be their home,” the palace said, in a statement. “From this autumn, however, the Duke and Duchess will increasingly base their family at Kensington Palace. As they have in recent years, their royal Highnesses are keen to continue to increase their official work on behalf of the Queen and for the charities and causes they support, which will require greater time spent in London.”
