Taking to Twitter, the Duke and Duchess of Cambridge shared an official statement released by Buckingham Palace just hours after Meghan had given birth.
It read: "Her Royal Highness The Duchess of Sussex was safely delivered of a son at 0526hrs. The baby weighs 7lbs 3oz and The Duke of Sussex was present for the birth."
The statement continued: "The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall, The Duke and Duchess of Cambridge, Lady Jane Fellowes, Lady Sarah McCorquodale and Earl Spencer have been informed and are delighted with the news.
The Duchess’s mother, Doria Ragland, who is overjoyed by the arrival of her first grandchild, is with Their Royal Highnesses at Frogmore Cottage.
Her Royal Highness and the baby are both doing well."
Meanwhile, it is believed Kate, who previously admitted to feeling 'broody' is keen to add to her family.
While visiting Northern Ireland back in February, the mother-of-three hinted that she would love to have her fourth child, before adding: "I think William might be slightly worried," she joked.
