Kylie Minogue was mobbed by male admirers after she performed with Rufus Wainwright on the grounds of the Hamptons Watermill Center on Saturday evening. The Australian pop princess performed a series of her hits and dueted with Wainwright on songs including “Carousel” classic “If I Loved You” and her anthem “Can’t Get You Out of My Head.” She wowed the 600-strong crowd that included producer Mark Ronson, actress Angelica Huston, Real Housewife Countess LuAnn de Lesseps and Stephen and Christine Schwarzman. The concert raised about $200,000 for the Watermill Center’s artist residencies and education programs. Wainwright closed the show with a touching version of “Over the Rainbow” dedicated to his late mother, folk legend Kate McGarrigle.
