Kate Middleton has always been full of glamour and an epitome of perfection since she joined the royal clan. The Duchess of Cambridge has always been gleaning the limelight and has millions of competitors around the world, but this time it's her own sister, Pippa Middleton!

The rifts between the two sisters continue to rise. It appears as if Pippa Middleton is pretty insecure about her own body and is recently trying to get back in shape so as to defeat her sister Kate in terms of fitness.

While Pippa Middleton's routine is jam-packed with wedding shenanigans, she still has the time to visit the gym that guarantees her a well-shaped, curved figure so that she can take the lead from her sister.

Pippa Middleton has her own anxieties. She obviously wants to be the bride of the time by maintaining a perfect figure with her toned legs. But based on recent speculations, Pippa Middleton is intimidated that Kate will overshadow her on Pippa's wedding day, making things worse between the sisters.

According to Celebrity Dirty Laundry, Pippa Middleton wants to look chic and maintains that she is different from Kate. And is willing to take on painful, intense workouts for the sake of her body and health.

According to Morning News, Pippa is doing so to become sexier than her sister. While talking about Kate, she has never been out of shape even after conceiving two children Prince George and Princess Charlotte. But she has never been spotted working out at the gym. However, Kate's younger sister is ready to break trends and she might be on the verge of setting a new record of being the sexiest bride to be.

Based on the pouring rumors, it can be said that Kate and Pippa have a turbulent relationship. Which is why, Kate might not be a part of her sister's wedding.
