Kate reveals that Princess Charlotte sang Happy Birthday to herself during at her 'little party'

Kate, the Duchess of Cambridge has given a candid insight into how her daughter Princess Charlotte celebrated her second birthday.

The mum-of-two made the adorable revelations during an official engagement at a farm in Gloucestershire, where children who had travelled from London were being taught various lessons about life in the country.

HELLO! magazine reports that teacher Natalie Graham gave Kate a card and gift that the group had made for little Charlotte, who turned two on the 2nd of May, and later recounted the story that the Duchess had shared about the occasion during their subsequent conversation.

'She told them that they had a little party for Charlotte yesterday and she sung Happy Birthday to herself!' Natalie explained. 'It was so sweet. She loved the card and present and said Charlotte would love it too as the card had Peppa Pig on, which she loves.'

Another attendee, nine-year-old Sayanna, who is fluent in Spanish, added that Kate told her that both of her children are already learning to speak other languages.

'She said she is trying to teach Charlotte Spanish and said her son George can count up to ten in Spanish already,' confirmed Sayanna. 'We also told her how we found all the cameras a bit strange but she said although it was weird she had got used to it.'

Tessa Stone, chief executive of the Farms for City Children initiative, said of Kate's visit: 'It's been a joy to have her for four hours. She spent quality time with the children and she was fantastic, you can tell she can really gets it. Having had a childhood experience growing up in the countryside, she appreciates how crucial it is.'

Earlier this week, a new portrait of the young princess was released to mark her second birthday, which clearly highlighted the Kate and William's strong rural values.

Charlotte is pictured clad in a traditional knitted cardigan and surrounded by hay bales in the sweet snap, which was taken by her mother at the family home in Norfolk.

Kensington Palace wrote a statement alongside the picture which read: 'Their Royal Highnesses would like to thank everyone for all of the lovely messages they have received, and hope that everyone enjoys this photograph of Princess Charlotte as much as they do.'
