Princess Eugenie, the Queen's granddaughter, marries Jack Brooksbank today in the second major royal wedding of the year.
Eugenie, 28, younger daughter of the queen's third child Prince Andrew and his ex-wife Sarah Ferguson, the Duchess of York, will tie the knot with Mr. Brooksbank, a 32-year-old drinks executive, at Windsor Castle.The ninth-in-line to the throne is following in the footsteps of the Duke and Duchess of Sussex, who also chose the venue for their wedding in May.
The ceremony will take place at 11 am at the castle's 15th Century St George's Chapel with the Dean of Windsor David Conner officiating.
Much of the pre-wedding talk has been focused on who won't be there - Prince Charles of Wales' wife Camilla, Duchess of Cornwall.
She is the only senior member of the Royal family confirmed to be missing the celebrations. It had not been confirmed officially confirmed whether or not Prince Philip, Duke of Edinburgh, would attend.
But he arrived at roars from the Windsor crowd.
His great-grandchildren Prince George and Princess Charlotte are set to take center stage as pageboy and bridesmaid respectively.
The traditional service, which will see Andrea Bocelli perform, appears traditional and serene on paper. But Princess Eugenie's rogue personality would suggest there may be some surprises along the way.
