Prince William refuses to be “hounded” by paparazzi.
The British royal and his wife Duchess of Cambridge Catherine Middleton are expecting their first child together.
Prince William’s mother Princess Diana of Wales died in a car accident in 1997 and was shadowed by the press throughout her adult life.
French magazine Closer printed topless pictures of Catherine as she and Prince William were enjoying a holiday in Provence in September, sparking international scandal and a lawsuit.
Prince William will not allow Catherine or his unborn child to undergo similar media pressure.
"William has always had a distrust, bordering on outright loathing, for the press," a source told Radar Online.
"It all stems from his childhood -- watching the way his mother was built up and then torn down by the media and ultimately, he strongly believes to this day, hounded to her death by overzealous paparazzi.
"He has vowed to do everything in his power to protect Kate from the media frenzy surrounding her pregnancy and Heaven help anyone who crosses the line. At William's behest the Queen instructed Palace bigwigs to individually call all of the chiefs at the British newspapers immediately following the pregnancy announcement and warn them, in no uncertain terms, that if any lines are crossed, any intrusive paparazzi shots are purchased and published, or if Kate feels hounded in anyway there will be hell to pay.
"William was deeply hurt and angered by the topless photo scandal Kate was forced to endure over the summer, and has made it crystal clear that, make no mistake, he will not allow his wife to be subjected to such blatant intrusion and humiliation ever again."
It's been fifteen years since Diana's passing, and a new film from Oliver Hirschbiegel, director of the Academy Award-nominated German docudrama Downfall, will explore what her final years were like.
The biopic Diana stars Naomi Watts, and focuses on her activism against land mines and her tumultuous romantic relationship with Dr. Hasnat Khan.
Diana is expected to hit theaters in 2013.
