Kate Middleton and Prince William are "more open" and "talk about their relationship together" amid her cancer journey, a source tells PEOPLE.

It seems as though the obstacles the Wales family was forced to endure have brought the Prince and Princess of Wales even closer together.

Earlier today, Prince William had an official royal engagement in London, in which he visited homelessness charity Centrepoint. Just hours after his public appearance, the Prince of Wales jetted off to Monaco where he was photographed watching his favorite soccer team, Aston Villa, compete in the UEFA Champions League.

When Kate Middleton celebrated her 43rd birthday on January 9, her husband Prince William wrote a tender message and shared it on the couple’s public Instagram account. According to royal expert Ingrid Seward of Majesty magazine, the display of affection was a sign that the couple has grown closer following Kate's cancer diagnosis in early 2024.

Meghan Markle talking about a tricky period in Princess Kate and Prince William's relationship caught attention on TikTok.

It was a royal treat. On January 10, Prince Harry and Meghan Markle made an unannounced visit to the Pasadena Convention Center, where displaced Californians were sheltering from devastating wildfires.
