Kate Middleton is still allegedly afraid that her royal life is about to end and it will be because of Prince William's ex, Isabella Calthorpe. The Duke of Cambridge and Calthorpe have been incessantly linked together after Prince Harry's rumored reunion with her half-sister, Cressida Bonas, who also happened to be Harry's ex.

Despite Kate Middleton and Prince William's best effort to mask their marital troubles, it appears that their relationship is still in crisis. According to Celeb Dirty Laundry, the 33-year-old Duchess of Cambridge felt threatened by Isabella Calthorpe since she was the Duke's preferred marriage choice. That's why, Kate is doing everything she can to stop Prince Harry from marrying Calthorpe's sister, Cressida Bonas.

Kate Middleton's fears intensified after things between her brother-in-law and Bonas started to heat up again after their reunion at Prince Harry's 31^st birthday celebration party. Life & Style magazine (via CDL) reported that Bonas spent the entire party at Harry's side. Unfortunately, their alleged reconnection was not because they have rekindled their romance. In fact, Daily Express noted that despite their breakup, the ex-couple remained good friends and share mutual pals.

A friend of the prince and Bonas also dismissed the rumors and insisted that they were out with a group of friends to celebrate Harry's birthday.

"Harry and Cress have always kept in touch and are fond of each other," a friend of the ex-couple said. "They aren't together at the moment and although you can never say never, I would be very surprised if it happened [again]. Cressida is very fond of him but, well, he didn't quite cut the mustard. The issues that were there when they broke up haven't changed."

It seems that Kate Middleton's fears are unwarranted since Prince Harry and Cressida Bonas are not getting back together. However, the Duchess can't seem to forget that she is Prince William's second choice. So, she will do anything to keep Isabella Calthorpe out of the picture. In spite of the fact that Isabella is married with a child of her own, Kate's constant comparisons with Princess Diana are likely making the Duchess paranoid.

Aside from marital crisis, Kate Middleton is also facing some style choice and makeover regrets. Inquisitr has learned that the Duchess was mortified by all the fuss people have been making just because of her bangs. But her stylist, Richard Ward, defended the look saying that bangs make an "instant style statement" and "they're ageless and timeless" since they would "never go out of fashion."

Meanwhile, Kate Middleton has successfully followed the footsteps of Princess Diana by receiving one of the Queen's highest honors, which is the Royal Family Order of Queen Elizabeth II. It is the highest honor the Queen can bestow upon a royal female and the Duchess has been a lucky and proud recipient, ET Canada reported.
