Get excited, royal fans — Kensington Palace has joined Twitter [1] and Instagram [2]! In the palace's first tweet [3], they explain, "This account represents The Duke and Duchess of Cambridge and Prince Harry — follow for updates on their work and the #RoyalFoundation." The Twitter feed is already full of must-see snaps of the royal trio, and some people are busy tweeting hilarious things [4] to the royal account. This isn't the first time Will, Kate, and Harry have gotten involved with social media, though. Prince Harry sent out his first tweet [5] last May, and he and Prince William made royal history [6] when they participated in a Google+ Hangout over the Summer. Does this mean more royal selfies [7] are on the way?
