Kate Middleton is clearly going her own way — without sister Pippa!

The wife of Prince William, 36, has gotten super close with sister-in-law Meghan Markle and Breaking Celebrity News has exclusively learned that “Pippa is incredibly jealous over Kate and Meghan’s relationship!”

“Meghan is turning to Kate for everything related to her pregnancy right now and Kate loves it because she is a very hands-on mother. She knows that Meghan wants to be too.”

“Because Kate and Meghan are bonding, this has made Will and Harry closer than ever,” the insider told Breaking Celebrity News.

Needless to say, Pippa, 35, who recently had a baby of her own with new husband James Matthews, feels slightly left out of the equation — and rightfully so!

As Breaking Celebrity News previously reported, mother-of-three Kate was “furious” when Meghan and Harry neglected to invite Pippa to their wedding!

But it isn’t just Meghan’s pregnancy that has brought the two royal ladies together!

“Kate was very lonely in the palace before Meghan came along. Meghan is bringing life into her and making Kate not so stiff and, for that, everyone is pleased.”

“At first the two were not in cahoots because Kate felt like Meghan was only in it for fame and status. But she has changed her mind about her,” the royal source revealed.

“Kate and Will both agree that Meghan is absolutely in love with Harry. And for that Kate will help her however she can.”
