"South Australia's camera-shy pop star Sia Furler enlisted American actresses Kristen Wiig and Dance Moms star Maddie Ziegler for her Chandelier performance at Sunday night's Grammy Awards at the Staples Centre in Los Angeles. Wiig, 41, seemed an offbeat choice of avatar for the 39-year-old Sia, who kept her back turned to the crowd. Wiig donned her signature platinum blonde fringed wig with an unflattering, tear-away jumpsuit for the interpretive dance. She wildly girated in a set resembling a broken-down apartment, featuring an overturned mattress and a light bulb-riddled ceiling. The similarly-clad 12-year-old Ziegler joined Wiig in a whirling dervish through the cluttered stage."
