There's no denying the royals are an elusive bunch, but they've been taking things to the next level of late.
The fab four, also known as Prince William, Duchess Catherine, Prince Harry and Duchess Meghan, stepped out in style last week, but we almost missed the entire event!
There's no denying it was a busy week for the royals - after attending several Remembrance Day ceremonies, the foursome attended Prince Charles 70th birthday celebrations on Wednesday.
Meghan and Harry also attended a black-tie event on Tuesday evening while Wills and Kate cooked up a storm for a charity supporting the homeless during the day on Wednesday.
But in another event that almost flew under our radar, the two royal couples glammed up for the Royal Foundation's annual dinner, which took place on Thursday evening.
Wearing a stunning bright red dress, Kate looked calm and collected as she and William posed for a photo with one of the event's performers - singer Tom Walker.
Meanwhile, Meghan and Harry also looked every bit the glamorous couple. The pregnant duchess wore a stunning black sleeveless gown and appeared fresh-faced, despite it being the third night in a row attending a black tie event!
Details about the event are limited, however along with Tom Walker, guests included BBC's Anita Rani who was the evening's host.
Kate's red dress was by British designer Preen, while Meghan's stunning black gown was by one of the Duchess' favourite designers, Rouland Mouret.
The glamorous duo have turned up the style stakes of late, with both being the talk of the town as they were snapped entering Charles' 70th birthday celebrations on Wednesday evening donning some serious bling.
The pair, who were driven into the event by their respective royal spouses, wore stunning crystal earrings with their hair styled in elegant up-dos.
A peep of Kate's dress was also visible as she entered the event, and while no full-length pictures were released of her outfit in full, royal fans have been quick to speculate which designer the mum-of-three opted for.
Given the pink detailing seen in the image, many believe the dress was designed by US label Marchesa. If this is the one, it's easy to imagine how divine it must have looked on the Duchess!
Despite their busy schedules, it looks like the young royals might be spending some quality time with their family this Christmas. Kate's brother James Middleton recently dropped a hint that Wills and his wife will be joining them for the festive season celebrations.
In an interview with German TV channel, Leute Heute, Kate's younger brother said he would "welcome people into our family home. I want it to feel like it's their home."
Meanwhile, Prince Harry and Duchess Meghan, who are expecting their first child next year, will most likely be joining in the festivities at Sandrigham.
