Taylor Swift Reveals Her Date To The Grammys

She'll sit in class next to red-headed Abigail.

We can finally stop speculating. Taylor Swift has revealed who she's taking to the 2015 Grammy Awards on Sunday.

Taylor is taking her childhood friend Abigail Anderson -- yeah, that Abigail. Remember the "Fifteen" lyrics "And Abigail gave everything she had to a boy who changed his mind/ And we both cried"? Taylor and Abi have remained friends since their high school days.

"We'll try to dress as well in 2015 as we did in 2005," Taylor wrote, announcing her BFF as her date to the Grammys, where she's up for three awards for "Shake It Off."

Scrolling through Abigail's Instagram, you can see how their relationship has evolved in the past few years.
