The Duke and Duchess of Cambridge start their eagerly-awaited tour tomorrow, heading to the Caribbean to celebrate the Queen's Platinum Jubilee year.
The couple have done many overseas tours and in 2016 even took a three-year-old Prince George and a baby Princess Charlotte on an official trip to Canada.
When the then-family-of-four arrived in British Columbia, on hand to greet them was Canadian Prime Minister Justin Trudeau.
But there was an awkward moment when George left Mr Trudeau hanging after going in for a high-five.
During the meeting, Mr Trudeau bent down to George's level and held out his hand for a high-five.
But the young royal looked unimpressed and shakes his head.
The Canadian PM tried again offering a low-five, which George also refused before going in for a more formal handshake.
But once again the young prince did not appear to want to indulge the Canadian leader.
The snub was far from causing an international incident, however. Mr Trudeau later tweeted that he and his wife Sophie were "honoured" to receive the royals.

George, Charlotte and their younger brother Louis are expected to stay at home during their parents' Caribbean trip.
Buckingham Palace confirmed last month that they would be travelling to the region for a week-long trip to help mark the Queen's Platinum Jubilee.
The tour will take in Belize, Jamaica and The Bahamas before ending on March 26.
A Kensington Palace spokeswoman said: “Their Royal Highnesses are very much looking forward to the visit, which will be their first joint official overseas tour since the onset of Covid-19 in 2020.”
The last week has been a busy one for both William and Kate.
On Monday they were at the annual Commonwealth Day service at Westminster Abbey with other royals.
Meanwhile, yesterday, they took part in the traditional St Patrick's Day Parade with the 1st Battalion Irish Guards.
William is Colonel of the Irish Guards and he and Kate have attended the annual event many times together in the past.
