Kate Middleton has seemingly spoiled her sister-in-law Meghan Markle's alleged attempt to dull her sparkle with a sensible move. "The Prince and Princess of Wales have made a sensible decision to put on united display, sending a meaningful message to those who are bent on ruining their happy moments," a source, close to the couple, has claimed. "William's heartwarming post for his incredible wife has marked the start of a new and hopefully happier year, and the end of one that has been brutal for the whole family. The picture would be memorable in so many ways," said the insider. It emerges after Meghan Markle shared an emotional post about her dog Guy's death day before Princess Kate's major milestone. The Princess turned 43 on January 9, celebrating her first birthday since completing preventative chemotherapy treatment. Princess Kate's special day was spoiled in the past years due to Harry and Meghan's shocking moves, according to royal commentator Jennie Bond. On January 8, 2020, the Montecito couple stepped down from their active working royal roles, "overshadowing" the future Queen's big day. Not only that, Harry released his bombshell memoir in January 2023, causing tension within the royal family. In 2024, the Princess of Wales was diagnosed with cancer and the rest of the year became challenging for the mother-of-three. Bond explained: Her [Kate's past few birthdays have all been rather overshadowed by events: Harry and Meghan announcing they were stepping back from royal duties on 8 January 2020, then Harry releasing his book, Spare, on 10 January 2023." But, in 2025, Kate has seemingly blocked the Duke and Duchess of Sussex's schemes. Undoubtedly, future Queen Kate Middleton emerges as a style icon in her new photo, which was released by her husband Prince William with heartwarming message, calling Catherine an "incredible wife." With the celebrations, Kate and William marked the start of a new and hopefully happier year, and the end of one that has been brutal for the whole family. Undoubtedly, Kate's 43rd birthday picture and message could be memorable in so many ways.
