Sister Of Honor! Pippa Middleton Heavily Reliant On Kate's Help

The Duchess of Cambridge knows a thing or two about how to throw a flawless wedding, and her bride-to-be sis, Pippa Middleton, is relying on every ounce of her expertise. Sources report that when Pippa weds hedge fund manager James Matthews on May 20, she’ll have her older sister, Kate, to thank for coordinating all the picture-perfect details. “Kate has been on hand for every flower choice and guest-list dilemma,” says an insider, who adds that Kate has devoted all of her spare time to Pippa’s preparations. “She’ll drop everything to rush over when Pippa needs her. She’s been involved in everything from flowers to favors,” “And she’s so good at calming down Pippa’s anxiety, it’s like she’s the wedding whisperer.”
