Kate Middleton was thrust into the public eye when she began datingPrince William.
“She has the knowledge and the poise,” the author added.
Why isn’t Kate Middleton called ‘Princess’?

Prince William and Kate Middleton are officially known as the Duke and Duchess of Cambridge.
But Prince William previously wanted his wife to hold a different title, according toThe Telegraph.
However, royal protocol stopped that from happening.

(Only direct descendants of the reigning monarch can take on “princess” titles,Expressexplains.)
This was, though, to reward her for years of loyal service."
Diana was officially given the royal title of Princess of Wales, the outlet explains.
(Charlotte is fourth in the royal line of succession, per theMirror.)
Although the Duchess of Cambridge misses out on this royal privilege, she already holds multiple royal titles.
Meanwhile, Kate’s royal title and name are reportedly set to change again when Queen Elizabeth II dies.
Perhaps royal fans will then refer to Kate as Princess Catherine, as William reportedly wanted.
