Sometimes technology really blows our minds - and one particularly hilarious use of tech is the FaceApp filter which allows you to see what you'll look like when you're much, much older!
As with all new face-changing apps, when they launch, celebs are some of the first to try the funny filters. While the royals never share the fruits of their experiments, we wouldn't be surprised if they had as much fun with new apps as we do. And here at HELLO! we've had a play around with FaceApp to see what the royals will look like in a few decades' time. Click through for the best results…
