Prince William and Princess Kate have been estranged from Prince Harry and Meghan Markle for nearly four years, but according to an insider, they “are open” to mending their relationship.

A source told Us Weekly that the couple is motivated by their children’s future, explaining, “They want a relationship with Meghan and Harry, and they don’t want the acrimony to carry over to the next generation.”

The sentiment appears to be mutual, as the insider added, “Obviously, the Duke and Duchess want their kids to have a relationship with their cousins.”

William and Kate share three children—Prince George, 10, Princess Charlotte, 8, and Prince Louis, 5—while Harry and Meghan are parents to Prince Archie, 4, and Princess Lilibet, 2.

Prince Harry is set to visit the UK next week for a ceremony marking the 10th anniversary of the Invictus Games, raising speculation about a possible reunion with William and Kate, who is currently undergoing cancer treatment.
