The royal couple are travelling to America this week in celebration of the second annual Earthshot Prize Awards.

William and Kate will arrive in Boston on Wednesday and will spend the following day sin the city attending a number of engagements before the awards ceremony takes place on Friday evening.
That seems incredibly unlikely, though. For one thing, William and Kate will be on the east coast of America, while Harry and Meghan reside in Montecito, on the opposite side of the country.
The Prince and Princess also have a jam-packed schedule, which will see them cover a large number of engagements during their whirlwind visit.
It's not yet known if Harry and Meghan will reunite with the royal family over the Christmas period.
However, his youngest son, his wife and their two children are not expected to make the trip back to the UK and look set to hold their own celebrations at home with Archie and Lilibet – and perhaps Meghan's mother, Doria Ragland.
Meghan recently revealed that when she was younger, her Christmas was spent helping the homeless or sick - and this may now be the way Archie and Lilibet are raised.
"Despite the contrast of my two worlds growing up, there was a powerful commonality: both my parents came from little, so they made a choice to give a lot," she revealed to People.
"Buying turkeys for homeless shelters at Thanksgiving, delivering meals to patients in hospice care, donating any spare change in their pocket to those asking for it, and performing quiet acts of grace – be it a hug, a smile, or a pat on the back to show ones in need that they would be alright."
