The Princess of Wales calls King Charles III “grandfather,” while the British monarch refers to Catherine as “my beloved daughter-in-law,” according to a biography by royal author Robert Jobson cited by RadarOnline and reported by life.dir.bg. The private nicknames reveal a surprisingly warm family dynamic behind palace walls that contrasts sharply with the formal public roles held by 44-year-old Kate and 77-year-old King Charles.
Charles Appreciates Catherine's Influence on the Royal Family
Robert Jobson’s biography details how the monarch routinely greets the future queen with a kiss and exchanges lighthearted jokes during family gatherings. A palace insider quoted in the book noted that Charles recognizes Catherine’s positive influence across the entire household. “I think that he understands that Kate influences the whole family. He loves her and truly appreciates everything she does,” the source shared.
Beyond her bond with the sovereign, the Princess of Wales plays an active role in smoothing over relationships within the royal household. Jobson highlights that Catherine has helped mend ties between Prince William and his father following periods of past strain. Rather than wading into personal disputes, she maintains a reputation for emotional maturity, patience, and an instinctive ability to understand competing perspectives.
That stabilizing presence took on added personal significance in 2024, when both Kate and King Charles publicly disclosed that they were undergoing cancer treatments, leading each to temporarily scale back public engagements. Meanwhile, the moniker “grandfather” extends directly to Charles’s relationship with the three children shared by Catherine and Prince William, even as the family guards the privacy of their domestic life away from media cameras.
