Pippa Middleton has announced her engagement to hedge fund boss James Matthews, and we are seriously excited about the wedding.
The Duchess of Cambridge's younger sister and her future husband will wed in 2017 - in what is set to be one of the most talked about society weddings since William and Kate tied the knot five years ago.
As is fitting for such a big occasion, we've got some burning questions we need answering...
1. Will Prince George be a pageboy and Princess Charlotte a flower girl?
Royal fans will hope the Duke and Duchess of Cambridge's children will play a part in their aunt's big day.
William was a pageboy at the wedding of the Duke and Duchess of York in the Eighties and was spotted misbehaving - sticking his tongue out and yawning.
2. Will Kate be the matron of honour?
Pippa shot to fame as the Duchess's chief bridesmaid in 2011. Ladbrokes has odds of 1-3 that Kate will be by Pippa's side as her matron of honour or bridesmaid.
Jessica Bridge, of Ladbrokes, said: "Pippa's finally found her Prince Charming and, as far as the odds are concerned, it's Kate's turn to return the favour and steal the show on the bride's big day."
3. Which venue will they choose?
The well-connected couple might call in a favour from a titled friend and marry at a private mansion.
But they could decide to get married abroad - James' parents own the luxury Eden Rock hotel on the Caribbean island of St Barts, or they could head to the Middletons' favourite destination, Mustique.
Pippa may want to be married closer to home, perhaps at the pretty St Mary the Virgin church near her parents' mansion in Bucklebury, Berkshire.
4. When is the big day?
It is thought unlikely that they will marry this year, with 2017 the favourite with the bookies - particularly late next year.
5. Will Spencer Matthews be best man?
The Made In Chelsea star, who is James' younger brother, once claimed to have slept with more than 1,000 women.
He hit the headlines last year after quitting I'm A Celebrity ... Get Me Out Of Here!, blaming an addiction to steroids. Bookmaker Coral is giving odds of 5-1 that Spencer will be chosen to stand by his brother's side.
6. Who will design the dress?
Kate opted for a lace bridal gown by Sarah Burton for Alexander McQueen. Will Pippa follow in her footsteps, or perhaps opt for a glamorous Vera Wang or an ethereal dress by Alice Temperley's label Temperley London?
British fashion designer Alice once described Kate and Pippa as "wonderful girls to dress and wonderful girls to be around".
Others in the running could be Sophie Cranston, of Libelula, or Bruce Oldfield.
Followers of Pippa's fashion style will also wonder whether she will opt for a figure-hugging dress. Her bottom gained attention when she was Kate's maid of honour and there are even websites dedicated to her derriere.
She once admitted: "It's startling to be recognised all over the globe because of your brother-in-law and your bottom."
7. Will they sell their wedding pictures to Hello! magazine?
William and Kate guard their privacy, but royal fans may be given a behind-the-scenes glimpse of the big day if Pippa agrees to a magazine deal.
Pippa has written for Hello! in the past, telling of her experience running a marathon in Kenya for the conservation charity Tusk.
Her brother James once appeared in a glossy spread in Hello! by baking several cakes featuring key front pages of the magazine to mark its 21st anniversary.
In 2008, William's cousin Peter Phillips was criticised for selling photos of his wedding to Canadian bride Autumn Kelly to Hello! for a reported £500,000.
8. Will the Queen attend?
It is unlikely, but Prince Harry might. Pippa and Harry are said to get on famously.
