He then gave us all the feels in a super sweet follow-up tweet: "Playing Meghan’s television partner for the better part of a decade uniquely qualifies me to say this: Your Royal Highness, you are a lucky man and I know your long life together will be joyful, productive and hilarious. Meghan, so happy for you, friend. Much love."
