The biggest stars in pop music strolled down the red carpet before last night's American Music Awards at the Nokia Theatre in Los Angeles. Katy Perry and Zoe Saldana covered up with floor length gowns, while other celebrities like Christina Aguilera, Taylor Swift, and Ke$ha took some red carpet risks.
Katy Perry made a statement in an unusual polka dot and floral gown from Oscar de la Renta, Spring 2014.
Ke$ha showed off a lot of leg in an elegant, floor length Michael Costello dress. Her striking, multi-color hair stood out against the stark black gown.
'Glee' star Naya Rivera looked sleek in a black silhouette from Michael Kors. The newly-engaged Rivera accessorized with a chunky gold cuff, and plenty of gold and jewel-toned rings. The gown displayed quite a lot of cleavage from the front.
AMAs Artist of the Year, Taylor Swift, glittered in a golden mini dress by Julien Macdonald.
Jennifer Hudson warmed up the red carpet with a leg-bearing fuscia and tangerine gown from Dior.
Actress Zoe Saldana wore an off the shoulder Roland Mouret gown.
Supermodel and 'Project Runway' star Heidi Klum wore an embroidered Marchesa gown, which she paired with Brian Atwood heels.
'Voice' judge Christina Aguilera channeled Marilyn Monroe in this racy white gown from Maria Lucia Hohan and sparkling Louboutin's.
