Britain's Prince Harry and Meghan Markle are getting married in St George's Chapel in Windsor Castle today.
Here's a full rundown of what will happen and what to watch out for.
EARLY MORNING: BEFORE THE WEDDING
As the sun (hopefully) rises over Windsor in the early hours of the morning, workers from street cleaners to police will be making final tweaks to plans to accommodate the 100,000 expected to descend on the town.
But Harry and his bride-to-be Meghan will make headlines hours before the phrase "I do" has been uttered or any champagne toasts have been made.
Like his brother and uncles before him, 33-year-old Harry will be granted a peerage by the Queen on his wedding day, with the Duke Of Sussex thought to be the most likely choice.
