The Princess of Wales is set to throw her support behind Prince William and one of his much-loved annual events.
The pair are set to appear at the Out-Sourcing Inc. Royal Charity Polo Cup 2023 at Guards Polo Club today, where William will be taking to the polo field.
Kate will no doubt be cheering him on from the sidelines and is expected to present the winning team with their trophies. But her afternoon out at the polo is likely to be a very different occasion to a similar polo event four years ago she attended with sister-in-law Meghan Markle.
On that day, they were at Billingbear Polo Club, Berkshire, to support William as well as Prince Harry and brought along their children for the afternoon.
Kate was pictured tending to Prince George, Princess Charlotte, and Prince Louis, with them at one point enjoying a picnic from their car boot.
Meanwhile, Meghan could be seen cradling a tiny Prince Archie, who had just been born a few weeks earlier.
That afternoon, neither woman seemed to interact with each other despite being in close proximity with their children.
And according to body language expert Judi James, they may have "deliberately avoided" each other.
Speaking at the time, she said: "What we're looking at appears to be two mothers wrapped up and lost in their own worlds. This could be a deliberate effort to avoid one another."
The expert did, though, stress this may be because Meghan might have been anxious not to disturb her sleeping son.
"We don't see any shots of Kate getting up to coo over the baby, which you'd expect," Judi continued. "Kate stays down, Meghan stays up and neither seems willing to meet in the middle.
"Instead, Meghan seems to stand alone and wary with a high protective grasp on her little boy - as if to say it's me and Archie against the world."
Since that day at the polo, Harry and Meghan quit their royal roles, left the UK, and have now set up a new life in the US.
And earlier this year, in his controversial autobiography, Harry lifted the lid on the relationship between his wife and sister-in-law.
He recounted several times when Meghan seemed at loggerheads with Kate in the early days of their romance.
He says the two women had a row over bridesmaid dresses in the lead-up to his wedding that left Meghan in tears and that Kate "grimaced" when the duchess borrowed her lipgloss.
Meanwhile, he wrote how Kate asked for an apology from Meghan when she accused her of having "baby brain" following the birth of Louis.
Harry's observation in Spare came after Meghan also took aim at Kate during her and Harry's Netflix docuseries, which was released last year.
As she recalled their first meeting, she said she was "surprised" by the behind-the-scenes formality of members of the royal family.
Speaking in episode two of the six-part Harry & Meghan Netflix, she said: "When Will and Kate came over, and I met her for the first time, they came over for dinner, I remember I was in ripped jeans and I was barefoot.
"I was a hugger. I've always been a hugger; I didn't realise that that is really jarring for a lot of Brits.
"I guess I started to understand very quickly that the formality on the outside carried through on the inside.
"There is a forward-facing way of being, and then you close the door and go 'You can relax now', but that formality carries over on both sides. And that was surprising to me."
