Prince William and Kate Middleton are some of the most popular British Royals today. Next to Queen Elizabeth II, the public highly approves of them and sees them as individuals with positive influences.

But, despite having enormous popularity and fame, they do not reportedly see themselves as celebrities. As stated, they have not "sought" fame, according to Fox News.

This insight on the Duke and Duchess of Cambridge's lives as royals comes after a new documentary about them emerges on screens. The material titled, Prince William: A Monarch in the Making, reportedly, features the "journey" of the future King of the United Kingdom, alongside his wife, Kate Middleton.

The publication then noted that the documentary also includes "special features" and interviews of individuals who are, reportedly, close to the royal-born Prince. These are all presented by royal correspondent, Royah Nikkah, the reports added.

Nick Bullen, who is the co-founder and editor-in-chief of the platform, True Royalty TV, reportedly, asserted that all British Royals deem themselves as non-celebrities. As it happened, they are "born" into the job, he added.

He continued to assert that unlike celebrities, who normally "crave the fame" or work to obtain it, royals have it "from day one." It is something that they can "never escape," he said.

Despite not seeing themselves as celebrities, royals, like the Duke of Cambridge, are, reportedly, "global celebrities" since the time they were born. But, while the rest of the world considers them as actual celebrities, Prince William and Kate Middleton have always prioritized their roles in the British Monarchy. "Duty comes first," Bullen explained.

In relation to fame and popularity, a similar notion was claimed by a royal biographer in the past, according to the Daily Express. As stated, the royal-born Prince "hated" every moment of his apparent fame during his teenage years.

Royal expert and author, Robert Jobson shared in his 2006 book, William's Princess, what happened to the future King of the United Kingdom when he became a "royal icon." As explained, Prince Charles brought his two sons with him in Canada months after the death of their mother, Princess Diana.

Their trip to the commonwealth country was, reportedly, the royal sibling's "first major public" appearance since the tragic death of the Princess of Wales. Upon their arrival, a new "phenomenon" was born. It became the now-known as "Wills Mania," the royal expert said.

As it happened, crowds of "frantic" young girls went "wild" when they saw Prince William. It, reportedly, became an "astonishing spectacle." However, he "hated" every second of it, Jobson claimed.
