Taylor Swift sat in at tonight's 2011 CMA Awards to deliver a solo acoustic performance of 'Ours,' pretty much confirming the rumors that the song from her 'Speak Now' song list is likely her new single.

Amidst Speak Now Tour dates across the country, Swift made a stop in her hometown of Nashville to give a stripped-down delivery seated on a couch. She was surrounded by lamps and wearing a laid-back pink sweater, which was a welcome break from the flashy lights and sparkly dresses filling the rest of the evening.

The young songstress did, however, light up the room with her pearly whites, and the couch, rug and lamp setup made the performance feel more personal and less like an arena show. After the song, the 21-year-old sat modestly while her country music elders presented her with with a standing ovation.

Swift is nominated for five awards at the 2011 CMA Awards, including Female Vocalist of the Year, Album of the Year, Song of the Year, Music Video of the Year and the sought-after Entertainer of the Year nod.

Late last week, Swift teased on Twitter that she had just wrapped a second day of shooting on a new music video, which it now seems is indeed the treatment for 'Ours.'
