Royal family members are said to have drawn up a rota to schedule when to visit Her Majesty at Windsor Castle while she mourns her late husband, and will no doubt be seeing her on her milestone birthday.
Her Majesty has also been relying on her two new puppies to keep her company and was even pictured taking them for a walk in Windsor on the eve of Prince Philip's funeral.
The Queen and the Duke were married for over 73 years and shared four children, eight grandchildren and ten great-grandchildren.
