Taylor recently topped two of the Billboard year-end country charts, as well. Red took the top spot on the Country Albums list, while its success and that of its subsequent singles earned her the title of No. 1 Country Artist. Additionally, the singer-songwriter came in third on the overall all-genre Top Artists chart, behind Adele and Rihanna, respectively.
The "I Knew You Were Trouble" singer was also recognized this year for her temperament. Nominated by cotillion students and directors nationwide, Taylor was named the Best-Mannered person of 2012 by the National League of Junior Cotillions.
Taylor will end the year in New York City, where she co-headlines the "New Year's Rockin' Eve" special with Carly Rae Jepsen. It airs Dec. 31 on ABC.
