Since Kate Middleton gave birth to her first child
 with Prince William, well wishes have been pouring in from the royal family
, the Obamas
, and more. It's been an exciting occasion for the monarchy as they welcome their newest addition, and the latest to congratulate the royals is Princess Diana's brother, Charles Spencer, who called the baby's birth
 "such lovely news."
Remembering when his sister gave birth to Prince William, Spencer recalled that he learned of the news while he was in boarding school at Eton. "The teacher rushed into my bedroom to tell me the good news, a bottle of champagne in his hands," he said. "Now, 31 years on, my wife and I are with all nine of our children, and we're celebrating this family addition with just as much happiness."
