Chanel's top fashion designer Karl Lagerfield slammed Pippa Middleton saying that he does not like her face and she should only show her back.

Karl Lagerfield always share his bold comments. The fashion designer made the headlines last February by criticizing singer Adele about her body by saying that she is "too fat." Lagerfield later apologizes to the singer.

This time, Karl Lagerfield complemented the Duchess of Cambridge while criticizing her sister for her appearance.

"Kate Middleton has a nice silhouette and she is the right girl for that boy. I like that kind of woman, I like romantic beauties. On the other hand, her sister struggles. I don't like the sister's face. She should only show her back," the fashion mogul boldly said.

Pippa Middleton became famous when she first appeared at the Royal Wedding last April. Her bum became a worldwide attraction and another reason to watch the wedding of her sister with Prince William.

The harsh comments of the fashion mogul angered the fanbase of Pippa Middleton and took their anger in Twitter and bashed Lagerfield.

Pippa, on the other hand, released no comment yet from the statements of the designer.

Kate and Pippa have always been in contrast with each other. While Kate is receiving all the complements, Pippa is receiving comments for her partying, dating a royal blood and her recently released book.

There were reports of sibling rivalry before. However, the two said they already make up and Kate is coaching her sister how to conduct herself in the United States.
