KATIE COURIC terrorize ANN CURRY according to a bombshell new book!

According to new tell-all “The News Sorority” by Sheila Weller, Kate Couric isn’t so sweet and gentle off-screen— especially around her onetime colleague, former Today show news anchor Ann Curry.

In the book, Weller claims Couric terrorized Curry, 57, before the co-host’s departure from the NBC morning show in 2006.

“Katie was a bully and Ann was the victim,” an TV insider told the author.

The mother of two, 57, allegedly slammed Curry’s style to her face.

“Katie often threw Ann off balance by criticizing Ann’s clothing choices just before they went on air,” Weller writes in her book.

When Couric became the anchor of CBS Evening News in the fall of 2006, the author claims she brought the tyrannical behavior along.

“She would look at someone and say, ‘I really think you’re clever, but why is your script so horrible?’” a CBS source told Weller. “She was mean. And no one was safe from her zinging.”
