Duchess Catherine flew back from the Netherlands on a British Airways economy flight.
The 34-year-old royal surprised passengers as she made her way home following her first solo engagement abroad by boarding a public aeroplane back to London’s City Airport on Tuesday evening (11.10.16).
The brunette beauty was greeted with mobile phones as she took her seat at the front of the aircraft in a stylish lavender suit and sat next to her bodyguards.
A source told the MailOnline, she had "never seen so many iPhones pop up at once".
Catherine – who has Prince George, three, and 17-month-old Princess Charlotte with Prince William – was the first to exit the plane and was picked up in a car, which was waiting on the tarmac to pick her up after the 50-minute flight.
On her first royal engagement without her husband, Catherine had dinner with King Willem-Alexander, Queen Maxima and their three daughters at their royal residence near The Hauge, Villa Eikenhorst.
She then met with deprived children at the Bouwkeet Makers Space in Rotterdam, Holland and showed off her repair skills at the centre, which aims to keep children off the streets and prevent crime in the neighbourhoods of Bospolder and Tussendijken.
The Duchess of Cambridge was then shown robots made of Lego constructed by the youngsters.
Catherine was introduced to nine-year-old, Driss Ben Mira, who showed the duchess the robot he had made called Meganoid.
Catherine congratulated the boy on his "amazing" creation and made him laugh by talking to the robot.
Looking at Meganoid, she said: "Very nice to meet you."
