While it is certainly a day for Queen Elizabeth to celebrate her record reign, she will also be giving another member of the royal family reason to as well. According to reports, Kate Middleton, who will be with husband Prince William and their children Prince George and Princess Charlotte in Scotland, will receive the Royal Family Order of Queen Elizabeth II – the highest honor that can be bestowed upon a female member of the royal family.

Kate is expected to travel to Balmoral with William, where the Queen and Prince Philip are currently residing, to receive the honor and mark her grandmother-in-law's big day. The Order she is tipped to receive is given to female royals directly from the Queen and serves as a personal memento rather than a state decoration, although it can be worn during state occasions.
Because there is no formal announcement regarding whether the honor has been bestowed, royal watchers will have to wait until Kate's expected attendance at next month's state dinner for China's President Xi Jinping to see whether she will be wearing it.

Previous recipients include William's late mother Diana, Princess of Wales and Prince Charles' wife the Duchess of Cornwall. Prince Edward's wife the Countess of Wessex has also been pictured wearing the Order to the wedding of Princess Madeleine of Sweden in 2013.
The Order depicts a younger Queen Elizabeth II in evening dress, wearing the ribbon and star of the Order of the Garter. The picture is painted on ivory and bordered by diamonds, while a Tudor Crown in diamonds and red enamel sits atop. It is sewn onto a chartreuse yellow bow and is usually pinned on the left shoulder of the recipient's dress.
