For their Spring and Summer 2015 campaign, fashion brand Saint Laurent have brought on a pretty exciting new model - none other than Joni Mitchell. The 71-year-old iconic folk artist was photographed in Bel Air by Hedi Slimane, and the photos are a part of the brand's "Saint Laurent Music Project" that Marilyn Manson, Courtney Love, Kim Gordon, and Ariel Pink have all taken part in already.
