>> ON THE CAMPAIGN TRAIL —While a horse of Steven Klein's caused Madonna injury over the weekend, another Steven — Steven Meisel — worked with a horse last week for one setting of the "marathon" four day Prada Fall 2009 campaign shoot at Pier 59 Studios in New York.  No confirmation on which models were involved, but a number of unconfirmed sources are indicating four girls — Kendra Spears, Anna De Rijk, Katlin Aas, and Miuccia Prada's current favorite, Ymre Stiekema.
