Duchess Of Cambridge Kate Middleton Unhappy About Prince Harry’s Rumored Engagement? Is She Afraid To Have The Spotlight Taken Away From Her?

If Prince Harry's rumored proposal to 24-year-old Cressida Bonas is true, then there is a reason for the Duchess of Cambridge to be threatened. This is because the talented alumna of the Laban Conservatoire of Music and Dance has a half-sister named as Isabella Calthorpe. Though half-sisters, the two can be compared to twins because of their closeness.

Prior to marrying Middleton, Prince William's subject of affections was Calthorpe. In 2007, the royal couple broke up which made the prince fall for Calthorpe further. The latter turned down the prince prompting him to go back to Middleton instead. One insider confirms how the duchess feels for Caltorphe: "Kate does not like Isabella because William loved her, and that caused their break-up. Bella's treatment at the royal wedding won't be forgotten."
 
Even if Caltorphe and her husband were invited to the 2011 royal wedding at Westminster Abbey, they were not given the privilege to attend the two prestigious receptions that followed.
Prince Harry has been dating Bonas for 14 months and according to a source who talked with British publication Grazia, the couple is already bound for marriage: "It's only a matter of time before Harry makes it official. They've discussed it at length together and with their families. Some of their friends reckon they might already be engaged but are waiting for a while to go public."
The blonde dancer is very much in love with the 28-year-old prince but the thought of becoming a princess reportedly makes her nervous. Nonetheless, constantly spending her time at the prince's apartment in London greatly helps.
"Harry has done everything to assure Cressida that she could cope. Living at Kensington Palace with Harry has helped. Harry loves Cressida and wants to settle down with her, so he's been preparing her for royal life in private," added the insider."
