The Middletons are, by all accounts, an incredibly close family. However, Princess Kate is reportedly skipping a party being hosted by her sister, Pippa Middleton, this weekend.
According to Hello! magazine, Pippa is currently "preparing for an intimate birthday celebration for her husband," James Matthews, who turned 51 on August 21. Pippa and James live at Bucklebury Farm in Berkshire with their three young children—Arthur, Grace, and Rose. The property is located near to the home of Kate and Pippa's parents, Carole and Michael Middleton.
