Princess Eugenie and Jack Brooksbank are set to tie the knot on Friday 12 October.
And 2018's second royal wedding is shaping up to be one of the biggest moments of the year!
Apparently the lovebirds want to make the most of their milestone, and spreading the celebration over two big days!
The Sunday Times have shared that after the wedding, the Queen will host a post-wedding lunch at Sarah Ferguson and Prince Andrew's home Royal Lodge at Windsor.
And the party won't stop there.
The very next day, Princess Eugenie and Jack Brooksbank's closest friends and family will let their hair down at an afternoon party.
The Sunday Times revealed that the bash is organised by A-list party planning firm Bentleys Entertainment.
An insider dished the event will be huge - "there will be everything from dodgems to funfair rides, as well as plenty of cocktails."
The wedding will be filled with some big names, including Kate Moss, the Beckhams and Naomi Campbell.
A source told the Mail, "The wedding itself is going to be huge and they are hoping quite a few of the people they've invited won't be able to come because of the capacity issue."
"There are rumours Ellie Goulding and Robbie Williams will sing."
