The pair have flown out to the Caribbean to join the rest of the Middleton family on their annual holiday, where they will celebrate her mum Carole's birthday!
But it seems Prince William is missing out on the trip with he studies at Cambridge University. We know where we'd rather be - we're in need of a bit of sunshine!
According to MailOnline, the six-month-old tot travelled with there family and three bodyguards on a scheduled 747 jet last weekend and apparently he was impeccably behaved during the flight. Aww bless!
And it's pretty important that Prince George gets used to travelling because he's expected to head to Australia and New Zealand when his parents complete their royal tour of the countries.
Wills is currently on a ten-week course studying agricultural management. But it won't be long before the family is reunited because Duchess Kate has her first official engagement of the year at the National Portrait Gallery on February 11.We hope we get another glimpse of Prince George soon! But in the meantime let's look back at some of Kate's best looks.
