Kate Middleton Attacked by British Author, Hilary Mantel, at Lecture Calls Duchess 'Shop-Window Mannequin' (AUDIO)

Kate Middleton was viciously slandered by one of Britain's revered authors Hilary Mantel, Reuters reported.

Mantel spoke at her lecture, titled, "Royal Bodies," in the British Museum on Feb. 4, and condemned the Duchess of Cambridge as a "machine made" doll  and "designed to breed" an heir to the throne.

The 31-year-old Duchess is pregnant with the royal couple's first child. 

"I saw Kate becoming a jointed doll on which certain rags are hung," Mantel said. "She was a shop-window mannequin, with no personality of her own, entirely defined by what she wore. These days she is a mother-to-be, and draped in another set of threadbare attributions."

Prime Minister David Cameron came to the Duchess' rescue, calling Mantel "misguided."

"She writes great books, but I think what she's said about Kate Middleton is completely misguided and completely wrong," Cameron said in an interview with Britain's Sky News.

Mantel, 60, is known for her critically acclaimed historical novel, "Wolf Hall," published in 2009 about the rise of Thomas Cromwell, a blacksmith's son, in Kinge Henry VIII's court between 1500 and 1535.

Several newspapers reacted to Mantel's comments as "venomous" and "publicity-seeking" and others on the social media thread said they couldn't agree more.  

Mantel said the Duchess was "irreproachable" and doesn't compare to William's late mother, Princess Diana.

"As painfully thin as anyone could wish, without quirks, without oddities, without the risk of the emergence of character," she said. "She appears precision-made, machine-made, so different from Diana." 

Her lecture at the museum was supposed to emphasize the media's role in crafting female monarchs into British models who are married into their lives and marked sources of pure entertainment.

A portion of Mantel's lecture took a delicate turn on how females are judged by their looks.

"It's actually a tender and sympathetic piece of writing, filled with compassion for royal women trapped in their gilded cages," said Daily Beast Royal writer Tom Sykes, reported The Huffington Post.
