WATCH: George, Charlotte and Louis speak publicly for the first time - hear their adorable voices!
The Cambridges' children were last seen publicly in photos released by Kensington Palace in September, as George, Charlotte and Louis got to meet one of their heroes, Sir David Attenborough.

The family-of-five enjoyed a staycation on the Isles of Scilly during October half-term, after previously visiting Tresco in the summer.
The week-long break got off to a fun start as George, Charlotte and Louis helped their parents to bake cupcakes, which were delivered to a Royal British Legion care home in Norfolk in support of the Poppy Appeal.
George, Charlotte and Louis made the Queen and Prince Philip a special card
The Cambridge children also showcased their artistic talents in the form of a homemade card for their great-grandparents, the Queen and the Duke of Edinburgh, as they celebrated their 73rd wedding anniversary last Friday.
Kensington Palace shared a close-up of the creation after Buckingham Palace released a new portrait of the monarch and her husband beaming at their gift from their great-grandchildren.
The card was emblazoned with the number 73, coloured in neatly by the three royal youngsters, surrounded by colourful polka dots.
