 Britain's Duke and Duchess of Cambridge have released a family photo with their son Prince George, a week ahead of their official visit to New Zealand and Australia. It is just the third official official release of photos of Prince George and shows him with his parents aged eight months at their home in Kensington Palace, London. The smiling duchess, 32, is holding Prince George on her knee as he focuses his attention on the family pet Lupo, a black cocker spaniel pictured sitting on the duke's lap. First tour 
 
 In the new image, the blond baby prince is wearing a pale blue jumper bearing his name, while his mother wears a cream-coloured blouse and his father a shirt with rolled-up sleeves. In the image, taken by royal christening photographer Jason Bell, the family is looking through an open window at their Kensington Palace home. The family will be in New Zealand and Australia from April 7 to 25 but it's unclear what opportunities the public in both countries will have to glimpse the youngest royal in person. He went to Christchurch shortly after it suffered an earthquake and also visited Queensland and Victoria, which had been hit by floods. The royal couple will board separate Team NZ America's Cup yachts for some informal racing in Auckland and coach rival teams in "rippa" rugby, a non-contact version of Rugby Union, in the South Island city of Dunedin.
– Ahead of their Australia-New Zealand tour next week, Prince William and Kate Middleton have released an official family photo that includes their now 8-month-old bouncing baby boy, reports the BBC. Prince George, who will accompany the royal couple on their trip beginning next Monday, is pictured being held by his mother in an open window at the royals' residence in Kensington Palace; William and the family pooch, Lupo, are at right in the image the palace says was taken by George's christening photographer, Jason Bell. As for the youngest royal's official duties on the Australia-New Zealand trek, well, it's up in the air, as per a palace statement via CNN: "George being just a little over eight months old by the time they travel, I'm sure you will appreciate that the couple will have to make a final decision on those moments much closer to the time." They will head out with an entourage of 11, notes the BBC, including a nanny and hairdresser.
