He has yet to be named, but Kensington Palace tweeted some details saying, "Her royal highness the Duchess of Cambridge safely delivered her son. The baby weighs 8 pounds 7 ounces. The Duke of Cambridge was present for the birth. Her royal highness and her child are both doing well.”
This new royal is the couple’s third child.
