Taylor Swift - ACM Awards 2010 Performance!

Taylor Swift is pretty in purple on the orange carpet at the 2010 ACM Awards at the MGM Grand Garden Arena on Sunday (April 18) in Las Vegas, Nevada.

The 20-year-old country cutie wore a wisteria Marchesa chiffon embroidered draped gown. She finished off her look with Christian Louboutin shoes and Neil Lane jewels.

Taylor performed her hit song “Change” with UCSD’s a cappella group, The Tritones. Halfway through the song, she ripped off her Carmen Marc Valvo dress and revealed a Charley 5.0 bustier, Hudson jean leggings and Everybody boots.

Yesterday, Taylor tweeted, “I just drove past Brad Paisley jogging down the side of the road. I rolled down the window and screamed RUN FORREST RUN. I live for little moments like that.”
