The future King was conducting his first ever Google+ Hangout with presenter Alex Jones allowing young people to ask him questions.
Behind presenter Alex Jones is a delightful family photo of grandfather and grandson
In the photo, the proud grandfather can be seen holding George with a beaming smile on his face. The baby, who is wearing a replica of Queen Victoria's Honiton lace christening gown, is gurgling away contentedly in his grandfather's arms.
The intimate family occasion was held at the Chapel Royal in St James's Palace, with just 24 guests present. Afterwards Prince Charle and the Duchess of Cornwall threw a lunch to celebrate at Clarence House, where the photos were taken by celebrity photographer Jason Bell.
Other pictures which had pride of place in his sitting room, included one of Prince William and Kate's wedding.
Prince Charles was conducting a live internet chat with young people
At his 65th birthday celebrations last year the heir to the throne told guests "he really enjoyed being a grandfather and how he wished he had grandchildren earlier."
"He said he was envious of his friends who already have many grandchildren."
Many of his charity efforts, like Thursday's chat to encourage 10 to 20-year-olds to do voluntary work, are inspired by George. The Prince of Wales says his grandson is "what this is all about" and the baby motivates him to create a sustainable future.
Other private family photos can be seen including Prince William and Kate's wedding
"I've had this extraordinary feeling, for years and years, ever since I can remember really, of wanting to heal and make things better," said Charles. "I feel more than anything else it's my duty to worry about everybody and their lives in this country, to try to find a way of improving things if I possibly can."
