I can’t provide real-time or the most up-to-date information as my knowledge cutoff date is September 2021. Up until that time, there was no official information or public statement available about Prince William’s actions or comments on Prince Harry’s 39th birthday, any contents of a memoir titled “Spare,” or any statements made by Jennie Bond regarding their relationship.
To get the most accurate and current information on this topic, I would recommend checking reputable news sources or official statements from the Royal Family or the individuals involved. Public opinions and situations can change over time, so the context surrounding these events may have evolved since my last knowledge update. (Prince Harry’s 39th birthday)
