The six-month-old baby appears on the cover of the latest issue of Hello! magazine in the arms of his mum the Duchess of Cambridge.
The image was snapped as Kate and George were disembarking a British Airways flight on the Caribbean island of St Vincent.
Mum and baby seemed to be in excellent spirits, soaking up some sun on the tarmac before boarding a private jet to Mustique, where they enjoyed a tropical holiday with the Middleton clan.
Kate and George flew first class, accompanied by two royal bodyguards and her brother James.
Her parents Carole and Michael Middleton and sister Pippa were already in the family’s Mustique villa, having caught an earlier flight.
William remained in the UK to continue his studies at Cambridge University.
Mustique is an extremely exclusive holiday destination, with just 74 villas on the whole island and one small hotel. It is a favourite of the Middletons, who are there celebrating Carole’s 59th birthday.
Kate and George returned to London yesterday.
