Taylor Swift American Music Awards 2013: Dress Looks Like Mischa Barton Frock (VIDEO, PHOTOS)

Who cares that Taylor Swift's ex is dating a Jenner sister?

The country pop star looked so over it when she attended the 2013 American Music Awards on Sunday night wearing a dazzling mini-dress that showed off her legs for days.

Swift stunned in the gold-and-silver Julien Macdonald frock that featured a nude-illusion lining on the chest and a chic matching belt.

Funnily enough, the 23-year-old's holiday party dress look eerily similar to a Versace that Mischa Barton wore in the ill-fated Ashton Kutcher TV show "The Beautiful Life: TBL."

Despite the similarities, Swift wasn't on the losing end of the AMAs. In fact, the five-time nominee took home trophies for Country Album of the Year for "Red," Favourite Female Country Artist, Favourite Female Pop/Rock Artist and also the coveted Artist of the Year Award for the third time.

How you like them apples, Harry Styles?
