Kate Middleton is having major sibling issues with Pippa. If latest reports are to be believed then it looks like the bond between the Duchess of Cambridge and her younger sister is going through a rough patch.

The buzz is out that Pippa is apparently upset with Kate because Prince William's wife is not using her royal connections to help her launch career or find love. Pippa Middleton, as we already know, is going through a bad phase lately, especially after her relationship with Swiss banker Nico Jackson came to an end last month. Her career too isn't flying very high.

"Pippa has been struggling to find her niche. Her party planning book, 'Celebrate,' flopped, and she has been unable to sell a follow-up exercise and diet book to a publisher. She attempted to land a position as a correspondent on NBC's 'Today' show, but she reportedly failed to impress during the audition," a source told Starpulse (via Inquisitr).

And now reports say that Kate is being held responsible for Pippa's break-up and failed career. Apparently, both Pippa and her mother Carole are upset with Kate for not using her royal connections to give Pippa's career a boost. In fact, the Duchess of Cambridge's mother is angry that her eldest daughter is not using her contacts to get Pippa married into an aristocratic family.

On the other hand, Princess Charolotte and George's mother is furious and embarrassed that Pippa Middleton continues to exploit her royal connections to get jobs among British aristocracy.

"The manipulative matriarch of the Middleton family is fuming mad that the Duchessof Cambridge is no longer acquiescing to Pip's ridiculous requests. Tension's running high in the Middleton family over this situation and Duchess Kate feels Prince William is the only person she can trust anymore," a palace insider told Celeb Dirty Laundry.

Well, if these rumours are true, then it looks like Kate Middleton has some serious issues with mother Carole and sister Pippa that need to be sorted out.
