Oh my AMAs!

Justin Bieber. was the biggest winner at the 40th Annual American Music Awards on Sunday Nov. 18. But before the 18-year-old nabbed three statues (including ones for Artist and Album of the Year), it was the women of the night that shined brightest on the red carpet -- literally!


Many of the A-listers opted for gold, silver and metallic hues for the fan-picked awards fest: Both Taylor Swift (in Zuhair Murad) and Heidi Klum (in Alexander Vauthier) went for similar gold mini-dresses, while Stacey Keibler (in Collette Dinnigan) and Hayden Panettiere both opted for similarly short dresses in a silver hue; Pink, meanwhile, went for a longer, pewter-toned metallic gown.

Nicki Minaj and Kerry Washington eschewed the sequins but were just as went for sunshine-yellow frocks on the red carpet. Country superstar Carrie Underwood went for dazzling purple in an Abed Mahfouz gown. (Christina Aguilera also favored a violet tone in a Pamella Roland number).
