Kate Moss has been banned by the Duchess of York from joining her family's skiing trip.

Sarah Ferguson was furious to learn that her daughter Beatrice had invited the supermodel to accompany them on the holiday, and soon made it clear that Kate couldn't come.

A source told the Daily Star, "Fergie was horrified because she feared Kate would be a bad influence on her beloved daughter. Bea absolutely adores Kate. They share a passion for skiing, so Bea thought she would be the perfect companion. Kate was very polite and said that she was delighted by the invitation.

"But Fergie has followed all the stories about Kate's alleged cocaine abuse and doesn't want her girl to mix with her. It would also attract a lot of negative attention from the media, which Fergie has successfully avoided for the past few years."
