Stars hit the world's biggest fashion runway on Sunday - the Oscar red carpet. This year's theme Metallic. Naomi Watts went metallic in Armani Prive Jennifer Hudson chose Roberto Cavalli; and Catherine Zeta-Jones was all gold. Whites and pale pinks were also on display with Charlize Theron in a Dior Couture gown. Anne Hathaway opted for Prada. Straying away from color, Adele - who almost always wears black - stuck with her color of choice on the red carpet.
