The Queen was disappointed when Prince William and Kate briefly separated in 2007.

Princess Kate recently paid tribute to the late Queen Elizabeth II during an official engagement in Windsor.

Kate donned a crimson double-breasted coat with black gloves, the same attire she wore to William's Sandhurst graduation in 2006.

Kate's brooch, similar to one worn by the Queen, held sentimental meaning.

Kate's decision to wear the brooch was a sweet nod to the late monarch.
