Born Catherine Elizabeth Middleton, Kate was given the title Duchess of Cambridge by the late Queen on her big day when she married into the royal family in 2011.
Following the death of her grandmother-in-law last year, Middleton's title changed once again to her current one, Princess of Wales.
Prince William's wife, who is one of the much-loved royals, could be assigned some important royal duties after the official crowning ceremony of King Charles and Queen Consort Camilla in May.
A new era for the United Kingdom will begin after Charles III's coronation on May 6. There are many speculations about Kate and William's future royal roles as some ask that Catherine’s title will change to "queen" when William becomes king.
The late Queen gave the world direction on how to address a person whose spouse becomes a monarch on her 70th anniversary on the throne in February 2022.
The Queen said in a statement at the time: "When, in the fullness of time, my son Charles becomes King, I know you will give him and his wife Camilla the same support that you have given me."
She added: "And it is my sincere wish that, when that time comes, Camilla will be known as Queen Consort as she continues her own loyal service."
Charles is expected to keep with tradition, Catherine will also take on the title of Queen Consort of The United Kingdom when William becomes king.
A consort, as per the official website of the royal family, is a person whose role is to "provide companionship and moral and practical support to the Monarch." Unlike a king or queen, a consort "does not hold a formal position in the structure of government."
Daisy McAndrew, NBC royal commentator, previously explained the difference in an email to TODAY, writing that a "queen consort is a woman who married a man who is king." Meanwhile, a "queen is a woman who is born to be queen and is head of state — not the wife of a monarch."
It means that Kate Middleton will never become a queen, but she could be called Queen by fans when her husband William ascends to the throne and the Princess will surely be providing companionship and moral and practical support to William.
