By officially, we do, of course, mean officially.
@KensingtonRoyal is today abuzz with live tweeting through Prince Harry's official engagement at sports event Coachcore, which bodes well for the future.
Will Kate start sharing mum-and-baby outfit posts à la Victoria and Harper? Will the royal Christmas selfie stick be taken for virtual spin? And, most importantly - will Wills live-tweet the birth of the newest royal?
Watch. This. @.
