Taylor Swift is still keeping her friend's memory alive all these years later... In case you didn't hear, the pop star's song Ruin the Friendship was a surprising heartbreaker on her album, The Life of a Showgirl. The song was written about her old school pal Jeff Lang, who tragically passed away back in 2010 at only 21. So, so sad. But all these years later, she's continuing to honor him and their special friendship in such a heartfelt way. Fans have been loving the tear-jerking tune for its poignant reminder to live without regrets and take risks, especially in love, while you can.
