The Grammys are going to be a friendly affair for Taylor Swift this year. The "Shake It Off" singer revealed who she's bringing as her date. And, no, it's not who you think — if you've been thinking about who she'll be bringing at all. Swift's bringing her bestie Abigail Anderson. Swift took to Twitter to make her big announcement today and promised to "try to dress as well in 2015 as we did in 2005." (A photo of the two playing dress-up was attached to the tweet. Fingers crossed her Swifties caught on to her sarcasm.) Anderson and Swift have been best friends since the 9th grade. She's appeared in a couple of Swift's music videos and has been at her side from the beginning. Swift told Oprah once that "[Abigail] wanted to be a swimmer and go off on a college scholarship for swimming, and I wanted to be a singer. Now she's off at Kansas on a swimming scholarship and I'm singing." And, now they're best friends attending the Grammy awards where Swift could potentially take home yet another couple ofgold trophies. Fingers crossed Anderson will pen an essay about her experience like Jennifer Lawrence's bestie did for the Oscars.
