Which is why the lovely couple recently added this $400,000 black Bentley car to their collection of rides!
The Flying Spur, which reaches a whopping 200 miles per hour, is what Will and Kate will be using to caravan them around London to their many fabulous royal engagements.
Among the car's many fancy features, it boasts wi-fi internet, back seat TV screens, a champagne bottle cooler, hand-crafted walnut wood interior and leather seats with heat and massage capabilities. And of course it has bulletproof windows and super hard steel armor to protect Prince George's parents while they are inside.
The whole car weighs a hefty three tons and only gets 19 miles per gallon of gas, but it's worth it to keep Will and Kate safe and comfy, right?
"The Bentley is being leased by the Duke and the Duchess of Cambridge and Prince Harry for official engagements, which is no different to any other member of the Royal family," a royal spokesperson recently told the Daily Mail. "‘The Royal Households lease a number of different vehicles from Bentley and Jaguar-Land Rover for use on official duties...We supply current Bentleys for use by a number of members of the Royal Family when the need arises."
The new parents recently used the posh Bentley to attend a reception at London's Natural History Museum last week.
In addition to their new Bentley, Will and Kate also have a Jaguar and a Range Rover, which they used to bring home their precious royal baby after he was born back in July.
