Actress Kristen Stewart attends the "Personal Shopper" press conference during the 69th annual Cannes Film Festival at the Palais des Festivals on May 17, 2016 in Cannes, France. CANNES, France -- In a pair of films at the Cannes Film Festival, Kristen Stewart makes a plaything of her celebrity, giving a homes-of-the-stars Hollywood tour in Woody Allen's 1930s-era tale "Cafe Society" and playing a fashion assistant in Olivier Assayas' psychological drama "Personal Shopper." Though "Personal Shopper" was met by a smattering of boos at its press screening in Cannes, Stewart has won raves for both performances.
