In 2008, the Grammy winner released an emotional song on her Fearless album titled 'Fifteen,' which was inspired by her high school best friend.

The 'Look What You Made Me Do' singer also celebrated her friend's engagement over Fourth of July weekend last year, complete with an 'ABIGAIL AND MATT ENGAGED!' banner.

Last February, Swift also served as maid of honour for her childhood friend Britany Maack as she wedded her husband Benjamin LaManna in Pennsylvania.
