Her parents and siblings may well be staying in their hometown of Bucklebury tonight as they prepare for the society wedding of the year tomorrow, but the Duchess of Cambridge was spotted driving through London on Friday afternoon.
It is thought that Kate attended the rehearsals for sister Pippa's wedding at St Mark's Church before driving her Range Rover back to Kensington Palace this afternoon.
Kate's children, Prince George and Princess Charlotte, are acting as page boy and flower girl at the nuptials tomorrow, so the mother-of-two most likely had plenty to organise back in the city.

It is unclear whether her husband, Prince William, or children were with her in the vehicle but the family-of-four will make an appearance together in Berkshire tomorrow.
Also spotted making last minute preparations for the wedding was Meghan Markle, Prince Harry's girlfriend, who was seen outside a Soho spa after flying into London to join her royal beau at St Mark's tomorrow.
Casually dressed in leggings, a hoodie, a baseball cap and shades - albeit with the addition of an expensive Mulberry handbag - the Suits star lingered outside the venue as she waited for a driver, likely to whisk her back to Harry's Kensington Palace apartment.

With less than 24 hours to go before Pippa and James say 'I do' in the society wedding of the year, their families descended on St Mark's church for a wedding rehearsal on Friday afternoon.
The bride's parents, Carole and Michael, were joined by their son James at St Mark's.
The Middletons were flanked by the Matthews clan - including best man and Made In Chelsea lothario Spencer - at the venue.
Prince George and Princess Charlotte's Spanish nanny, Maria Borrallo, was also seen arriving as the wedding party sheltered under umbrellas when the heavens opened - weather that is forecast to last all weekend. Prince George will act as page boy and Charlotte as a flower girl but neither the youngsters - nor their parents - appeared to be in attendance at the run-through.
Photographs also revealed lighting on a par with that of the average theatre attached to the ceiling of the glass structure

A Green Parlour florist van - the same company that Kate enlisted for the Royal Wedding in 2011 - was seen arriving at St Mark's Church on Friday ahead of Pippa and James Matthews's wedding.
Whilst it hasn't been confirmed who will be providing the blooms for Pippa's big day, Berkshire-based Green Parlour is an obvious choice considering they've been the Middleton's family florist for years.
Run by Emma Sampson, Green Parlour apparently supplied the Middleton family with flowers for four years prior to preparing the blooms for the Royal Wedding.
Members of the wedding party - who could well be James's ushers and groomsmen - were seen arriving at the church for a final run-through before the society wedding of the year

Whilst prices for wedding flowers are totally bespoke, bouquets on her website are reasonably priced between £35-£75.
Bridebook founder Hamish Shephard, who has organised many society weddings, predicts Pippa's flowers could set her back £16,000.
Hamish said: Marquees always require a lot more floristry and decoration than a venue, so luxury florists will have their work cut out. On top of this, the wedding florist will include the flowers for the church, plus the bouquet and more.
'With the wedding hosted in the Middletons' rustic garden, with wild flower meadows and in-bloom purple rhododendrons, expect tall overflowing centrepieces fusing the marquee with the garden. Elaborate table-centres can cost £300 each alone, so with 35 round tables for the guests, the cost can easily stack up.'
Emma, who is in her early thirties, said she had been called by the Duchess of Cambridge and asked to help with the wedding. She told the BBC at the time: 'Catherine asked us herself and it was wonderful, I mean, what an honour to be asked to do such a fantastic event and use some amazing flowers hopefully as well.'
On her website, Emma writes: 'Flowers have been a huge part of my life since I was at school. Before opening Green Parlour Florist I picked up a degree in fine art, gave flowers up and began working as a manager for Gap and French Connection, but flowers were always at the back of my mind.
'In 2008 with the support of Paul and Margaret, we opened the doors to Green Parlour Florist in Reading and I’ve been lucky enough to do what I love ever since. We’ve grown employing six people who are as obsessed with flowers as us.
'We’ve worked with amazing people during this time most notably receiving a call from HRH The Duchess of Cambridge to ask if we’d kindly help with the flowers for the royal wedding.'
MailOnline has contacted Green Parlour Flowers and is awaiting a response.

It's being touted as the society event of the year so it's hardly surprising that the church grounds surrounding Pippa Middleton's wedding venue went into total lockdown on Friday.
Metal barriers - thought to be in place for Pippa and James's big day tomorrow - were erected around the church as security arrived on the scene just 24 hours before the couple will say their vows at St Mark's Church in Bucklebury, Berkshire.
The last-minute preparations come after workmen appeared to be making some last-minute improvements to the church and gardens where Pippa and James will tie the knot.
The installation of the barriers comes after a fleet of Bentley Bentayga 4x4 were delivered to Englefield House earlier this week, which could well be the cars that will ferry guests from the church to the Middleton family home a few miles away for the evening reception.

A gardener was seen mowing the lawns for the second time this week, whilst workers were spotted cleaning and fixing the church's sign - preparations that are thought to be taking place ahead of the society wedding of the year.
With just days to go until their big day, Pippa Middleton and her fiance James Matthews have been spotted out and about making some final preparations.
Pippa Middleton was seen driving through the rain with her mother Carole this week near to St Mark's Church in Bucklebury, Berkshire, where the wedding will take place on Saturday.
The Mail today revealed that the wedding with have a Scottish theme. Pippa’s links to God’s Country are a little unclear – although she did go to Edinburgh University.
Groom James Matthews, however, is better connected and it would seem this has driven the plan for the nuptials.
James’s father, David, a former mechanic who made a fortune through the car trade, owns a castle and 10,000-acre estate 15 miles from Loch Ness in the Highlands.
His acquisition of the property in 2008 also bought him the courtesy title of the Laird of Glen Affric, which will be inherited by his eldest son, hedge fund boss James. That would make Pippa Lady Glen Affric one day.
Friends say Pippa and her fiance have a deep love of Scotland and often spend time at the Matthews family estate, where they hold annual shooting parties at the Glen Affric Lodge.
As a result the 300 guests at the wedding are set to enjoy a wealth of food sourced from the region around Glen Affric, including haggis canapés and lamb, all washed down with local whisky.
The guests will need a method of transport to travel between the church and the Middleton family home and it could well be these plush 4x4s
Around 100 guests are thought to be attending the church service, with 300 joining at the party later on in the evening
