The red banners have been draped over the balcony at Buckingham Palace. The trees have been taken inside Westminster Abbey for Kate Middleton's fairy-tale walk down the aisle. The red carpet has been rolled out. And the guests are just starting to arrive at Westminster Abbey to watch the royal wedding.

Wedding gossip tells us that the very first hymn to be played at the nuptials was the very last hymn played at the memorial service for Princess Diana. Crowds have been gathering around Westminster and Buckingham in London for days, hoping to catch a glimpse of the popular royal couple being married today. William is Diana's oldest son, and very beloved to the English people since he was born. William and brother Prince Harry greeted gathering crowds the night before the wedding (though rumor says that Harry still hadn't finished his best man speech at the time!).

Prince William obtained royal permission from his grandmother the Queen to use the trees to line the aisle. They will be re-planted immediately following the ceremony.

Queen Elizabeth II is one of the many English monarchs wed in Westminster Abbey. Princess Diana's memorial service was also held here.
