The Prince and Princess of Wales' relationship famously began at the Scottish university of St Andrews where the pair met as two young students as they took up residence in St Salvator's Hall.
Their on and off relationship lasted for nearly a decade before Prince William finally popped the question and proposed to Kate during a romantic trip to Kenya.
While there was widespread speculation about the strength of their relationship for many years, the couple were officially engaged on October 20, 2010 but they would leave the rest of the world waiting for another month to hear the news.
