There were reportedly three women who made Kate Middleton angry.

The Duchess of Cambridge is always graceful and elegant. She’s always smiling whenever she steps out. However, according to Express reporter Emily Hodgkin, there were three women who triggered the duchess’ wrath.

Here are the women who made Middleton angry.

Isabella Calthorpe

In Katie Nicholl’s 2010 book “William and Harry,” the author revealed that Isabella Calthorpe caught Prince William’s attention during his trial separation with Middleton. Isabella had the cover-girl looks, title and stately pile.

Prince William reportedly made “amorous advances” toward Isabella, but she turned him down because she was not interested in joining the royal family. The royal expert added that Isabella was the only woman who could make Middleton jealous.

“She is the one woman who turns her green with envy and incites a wave of panic at the very mention of her name,” Nicholl wrote.

When Prince William and Middleton got back together, she reportedly made it known to the future king that she was not happy with his advances to Isabella. She also told Prince William to never contact her again.

Carly Massy-Birch

Prince William and Middleton met at the University of St. Andrews in 2001. According to Nicholl, the Duke of Cambridge was sending mixed signals to Middleton and Carly Massy-Birch at the time. The royal biographer added that Middleton “could not stand” Carly.

Prince William and Carly were living near each other and it didn’t make Middleton happy at all. In fact, the duchess “grated on” the thought of it.

“They could literally wave to William from her sitting room where she would sit knitting by the window, which rather grated on Kate,” Nicholl added.

Rose Hanbury

According to The Sun’s executive editor Dan Wootton, Middleton had a “terrible falling out” with Rose Hanbury, the Marchioness of Cholmondeley. Middleton was so angry that she didn’t want to see her again and allegedly asked Prince William to “phase out” Rose from their inner circle.

Middleton and Rose’s rivalry were first reported weeks ago. The Duchess of Cambridge was reportedly threatened by her ex-model neighbor as she vied to be the queen bee of the Turnip Toffs.

Daily Mail’s Richard Kay debunked the rumors. According to him, Middleton and Rose were never close, but they liked each other. The two were reportedly considering legal actions and the speculations were only made to damage the Duchess of Cambridge.
