The two royal couples known as the "Fab Four" – Prince William and Kate along with Prince Harry and Meghan – have taken another step to divide their work.
Prince Harry and Meghan are leaving the Royal Foundation, the charitable organization they shared with Prince William and Kate, and will establish their own charitable foundation, according to Kensington Palace.
The Royal Foundation will become the "principal charitable and philanthropic vehicle" for William and Kate, the palace said in a statement.
The Royal Foundation was the organization under which the two couples ran several joint charities, including their Heads Together mental health initiative that William, Kate and Harry launched in 2016.
The royals are planning to still work together on certain projects in the future, including Heads Together, according to Kensington Palace.
"These changes are designed to best complement the work and responsibilities of Their Royal Highnesses as they prepare for their future roles, and to better align their charitable activity with their new households," the palace said.
The split of the Royal Foundation comes nearly four months after William and Harry split their royal households.
The Duke and Duchess of Cambridge, William and Kate, who share three children, remained based at Kensington Palace. The Duke and Duchess of Sussex, Harry and Meghan, who welcomed their son Archie in May, moved their staff and resources to Buckingham Palace, reporting to Queen Elizabeth II.

William is preparing to be king while Harry is growing his family and focusing on his and Meghan's initiatives.
Harry and Meghan also recently moved from Kensington Palace, where they were neighbors with William and Kate, to Frogmore Cottage, a royal household in Windsor, about 25 miles from London.
Meghan, who is now on maternity leave, set her charitable focus earlier this year, becoming the royal patron of four charitable organizations, focusing on women, young people, animals and the arts.
She became a patron of the Royal Foundation when she and Harry wed May 19.
Just before the wedding, Meghan joined Kate, William and Harry at a forum to talk about the work of the Royal Foundation.

"When we first started, it started as a very small idea and started with Harry and I scratching our heads thinking how can we do something for the future."
The Royal Foundation, established in 2009, is focused on four core areas of young people, conservation, mental health and Armed Forces, according to its website.
In addition to Heads Together, the foundation also oversaw the Invictus Games, Harry's Paralympic-style sporting event for wounded service people, and the royals' conservation efforts such as United for Wildlife.
William, Kate, Harry and Meghan last appeared together on June 8 for Trooping the Colour, an annual celebration of Queen Elizabeth's birthday.
