Philippa Gregory Philippa Gregory

Author Philippa Gregory has become an authority on British royalty, but her interests don't necessarily extend to the present.

"I'm utterly indifferent about Kate Middleton's baby," she confessed at Starz's Television Critics Association fall previews on Friday. "It know this is terrible. It's like blasphemy!"

Gregory isn't really anti-baby and is glad that little George is healthy. "I'm also extremely glad for his sake that it's a boy," she added. "It's going to have a terrible life, and if it had been a girl, it would have been a nightmare."

The author is instead focused on bringing the historical royals to light. "You're so nice to think that British people are so well informed and understand anything about history," she told an American critic who wondered if stories of the kings and queens were common knowledge in the U.K. "On some levels, we're quite dumb... Some get their info about Henry VIII from Jonathan Rhys Meyers [from Showtime's The Tudors]."

Gregory's novel series The Cousins' War is the basis for Starz's new historical drama The White Queen, which follows the women involved in The Cousins' War, which was later dubbed the War of the Roses by Sir Walter Scott. The White Queen stars James Frain, Rebecca Ferguson, Janet McTeer and Max Irons and premieres on Saturday, Aug. 10 at 8/7c on Starz.

Gregory is best known for The Other Boleyn Girl, which was adapted into the 2008 film of the same name starring Natalie Portman and Scarlett Johansson.
