The couple married at Westminster Abbey on April 29 2011 after an eight-year relationship. Prince William’s marriage to his former university flatmate was the royal event of 2011 as 2,000 guests filled the abbey. The grand affair featured two dresses, two receptions, a carriage procession through central London, flypasts and two kisses on the Buckingham Palace balcony. Nearly 25 million people in the UK tuned in to watch the live televised ceremony, with the worldwide TV audience estimated to be two billion. Twelve years on, the couple have three children, Prince George, aged nine, Princess Charlotte, seven, and Prince Louis five.
