Queen Elizabeth II has joked that Princess Charlotte loves to boss around her big brother Prince George.
The Queen made the comment at Sandringham House in Norfolk after asking if a schoolgirl she was presenting with a Bible "looked after" her little sister.
The girl's mother replied that it was "the other way around", prompting the Queen to say: "It's like that with Charlotte and George."
Her comment echoes a reported remark by the Duchess of Cambridge who claimed in March last year that her daughter was "the one in charge".
The Queen made the comment about her great granddaughter to Ellen Clay, 38, who was at Sandringham to watch her daughter Emily, ten, receive a Bible.
Mrs Clay said: "She asked if Emily looked after Hadleigh and I said it was more the other way round. She said it was like that with Princess Charlotte and Prince George."
Insurance worker Mr Clay added: "The Queen was implying that Charlotte keeps an eye out for George rather than the other way around. It is often the case that a younger child is more confident. It is second child syndrome."
