The Duchess of Cambridge has revealed the "feisty" side of her one-year-old daughter Princess Charlotte.
Kate Middleton chatted about the toddler as she attended a reception at the Guildhall in the City of London following the National Service of Thanksgiving for the Queen's 90th birthday at nearby St Paul's Cathedral.
The Duchess, who was wearing a stylish pale blue custom-made Catherine Walker coat dress embellished with white lace applique and a Jane Taylor hat with her hair in a chignon updo, told Glynis Double that she hoped Prince George would keep his younger sister in check.
Double said: "The Duchess was saying how happy she was to be here and how lovely the service was.
"As a mum myself I asked her about her children and said what a pretty little thing we all thought Princess Charlotte was.
"She said 'Oh she is very cute, but she has got quite a feisty side.'
"I then asked her about George and she said he was a really lovely little boy. She said she hopes that George will keep Charlotte in order."
Double, who was accompanying her husband Paul, who holds the role of the City of London Remembrancer, said she had no idea the Duchess and the other royals would be mingling with guests.
"It was such a surprise to be introduced to her and she was just lovely - and very, very beautiful," Double added.
"She kept on asking if we had enough to eat - and I told her we hadn't stopped since we arrived.
"As my husband has been involved in organising the event I really couldn't be prouder."
