Heartbreaking reason Kate Middleton blamed herself for Pippa Middleton romance split

The Princess of Wales felt responsible for the end of one of her sister’s relationships – and it threatened to tarnish her very first Christmas with the royal family.

Kate was invited to join the late Queen at Sandringham for the festive season in December 2011. And while it was an exciting time for Prince William’s new wife, she reportedly felt sad to be separated from Pippa who had split with her boyfriend Alex Loudon just one month earlier.

Writing in her 2013 book, Kate The Future Queen, Katie Nicholl said that the Princess missed her family, noting: “She was particularly sad not to be with her sister, who was heartbroken after having recently split up with Alex Loudon.”
