Taylor Swift has secured herself one amazing date to this Sunday night's Grammy Awards, but it's not who you might think. While the singer has a multitude of BFFs she could have at her side (Karlie Kloss, Selena Gomez, Lena Dunham, to name a few...), she just revealed her plans to take longtime childhood pal Abigail Anderson, for whom Swift wrote her hit song "Fifteen."

The superstar announced the news on Instagram earlier today, where she shared a throwback picture of the pair dressed up in shimmery gowns and sparkling tiaras. "My date to the Grammys is........ @abigail_lauren!! We'll try to dress as well in 2015 as we did in 2005. #GetReady," she captioned the snap.

While Swift will not perform at the Grammys (she recently announced that it’s because she’s too busy prepping for her 1989 World Tour), she still plans to attend and will present the award for Best New Artist.
