The big day is finally here! Prince Harry is marrying the woman of his dreams, American actress Meghan Markle in the most anticipated Royal Wedding since Prince William and Duchess Catherine wed in 2011.
As we count down to Meghan Markle's grand arrival and the first look of her wedding dress, a wave of activity is happening outside of St George's Chapel, Windsor Castle.
Shortly, names like Victoria and David Beckham, George and Amal Clooney and Elton John will be leading the celebrity contingent of guests arriving at the chapel. Tennis star Serena Williams has already Instagrammed a photo of herself getting ready for the big day.
Kensington Palace have shared the first glimpses of the majestic floral creations dreamt up by Philippa Craddock, posting a photo of the entrance of the chapel adorned in an array of white roses, lilies and lush greenery.
In the hours leading up to the wedding, the palace have finally confirmed the couple's official titles: The Duke and Duchess of Sussex, the Earl of Dumbarton and Baron Kilkeel.
The statement from Buckingham Palace reads: "The Queen has today been pleased to confer a Dukedom on Prince Henry of Wales. His titles will be Duke of Sussex, Earl of Dumbarton and Baron Kilkeel."
"Prince Harry thus becomes His Royal Highness The Duke of Sussex, and Ms. Meghan Markle on marriage will become Her Royal Highness The Duchess of Sussex."
Prince Harry and Meghan Markle will say "I do" at 1pm UK time (11pm NZ time) in front of 600 friends and family in an hour-long religious ceremony.
The couple will be married by the Archbishop of Canterbury The Most Revd. and Rt Hon. Justin Welby, who has previously spoken of the pair's "profound sense of commitment" to each other.
While the wedding service will be delivered by the Rt Revd. David Conner, the Dean of Windsor.
They'll then make their dazzling debut as husband and wife on a horse-drawn carriage, which will work its way around the town centre so well-wishers can catch a glimpse of the newlyweds.
The planned route will snake around Castle Hill, the High Street before heading back to the Castle via Long Walk.
