Kate Middleton, Camilla, Duchess of Cornwall and Queen Elizabeth have been keeping busy ever since First Lady Dr. Jill Biden and President Joe Biden arrived into town.
On Friday, June 11, the three ladies first attended a reception for world leaders before heading to another bash for the Big Lunch initiative.
The royals interacted with volunteers who are encouraging people to meet up for meals and community bonding. These people will put together the Platinum Jubilee, which will occur next year.
In the photos obtained by PEOPLE, Kate, 39, wore a white dress, while Camilla, 73, sported a patterned frock and the matriarch, 95, donned a floral outfit. The Queen appeared to be cutting into a big cake at the outing.
Kate even paid tribute to Princess Diana by wearing a three-strand pearl and diamond bracelet that once belonged to the late royal.
Earlier in the night, the three women were spotted with Prince William and Prince Charles as they met with U.K. Prime Minister Boris Johnson.
Kate and Dr. Biden met earlier in the day to talk about education.
"Welcome to the UK, @FLOTUS 🇬🇧🇺🇸," the Duke and Duchess' official Instagram account captioned a slew of photos. "It was great to host Dr. Jill Biden and experts from the UK and the United States for a discussion on the importance of early childhood on lifelong outcomes, and how we can work together to make a difference."
The message continued, "The importance of providing support for parents and children alike during early childhood, and the positive impact that this can have across society, is something we share a great passion for. Next week, The Duchess is looking forward to sharing a major announcement about how she is working to elevate the importance of early childhood and continue the conversation on this vital issue."
