A Facebook post about Catherine, Princess of Wales, directs readers to an article claiming that she and Prince William are expecting a fourth child. The linked story supplies no dated statement from Kensington Palace, no named spokesperson and no recording or transcript of a public announcement. The Royal Family’s public biography lists three children, Prince George, Princess Charlotte and Prince Louis. The material accompanying the post does not establish a fourth pregnancy.

The headline and the body also tell different stories. The Facebook headline suggests a distressing development, while the linked article describes what it calls joyful family news. Neither tells readers when the alleged announcement took place or where to find the original words. That omission matters because an announcement can be checked only if readers can identify who made it and when. A post that merely says a public figure has confirmed something leaves those questions unanswered.

The Royal Family’s biographies describe Catherine’s public duties, charitable work and family life. They provide a record of what the household has chosen to put on the public record. The press release archive is a separate place to look for dated announcements. For example, when the household announced the birth of Princess Eugenie’s daughter in August 2026, it identified the parents, provided the date and gave details that readers could trace to the original release. That announcement concerns a different family and gives no support to the claim about Catherine.
