Pippa Middleton promoted her party-planning book Celebrate by allowing reporters to document a crafting session including her in plain clothes and a handful of children wearing Halloween costumes. (For the record, Pippa's book includes groundbreaking Halloween decorating tips like, "haunt gardens, attics, and stairways with ghosts made from sheets.") An tense moment ensued when one little girl at the table wearing devil horns told Pippa, "I hate princesses." The child continued, "I like vampires." Cute!!!
