Multiple sources confirmed to ET on Wednesday that Swift and her boyfriend of one year, Calvin Harris, have called it quits. While we may mourn the loss of a fan-favorite celeb couple, let's take solace in the promise of what will undoubtedly be a glorious follow-up to Swift's epic 1989. (Is it too soon to pre-order this album?)
Over the last 15 months, the pair had been generous in sharing many major relationship milestones with fans through social media, giving us all a few big clues in to what topics Swift might tackle next in her songwriting. Read on for our best bets.
1. The Beginning Ellie Goulding introduced the pair at the Elle Style Awards on February 24, 2015. Clearly, it didn't take long for sparks to fly! The former couple declared their official anniversary as March 6.

2. Going Public
By May, the pair went public with their relationship by stepping out together at the Billboard Music Awards. Harris looked absolutely smitten with his lady -- who took home eight awards that night -- embracing her in a few extra-long congratulatory hugs.
But as we all know, a relationship isn't official until it's social media official. The duo formerly known as "Tayvin" crossed that bridge in June with a devastatingly adorable Instagram pic involving an infinity pool and an inflatable swan.
One simply cannot love Swift without also loving her two adorable cats -- Meredith Grey and Olivia Benson. And Harris did just that! The EDM superstar seemed to embrace the role of "cat sitter," staying home to keep the felines company while Swift was in Europe for her 1989 World Tour.
Eagle-eyed fans spotted a more direct "I love you" that seemed to be aimed straight at Harris during one of Swift's Los Angeles shows. The singer appeared to mouth those three little words from where she was strutting on the catwalk, as Harris beamed from the audience.
The duo showed off even more international PDA with a sweet Fourth of July-themed snap, which Swift cheekily captioned "Friendly relations between Scotland and America."
Swift and Harris seemed to build some happy holiday memories last year, when Harris joined Swift (and her family!) on a Christmas vacation in Colorado. They even posted a sweet snap of a snowman they built with the "New Romantics" singer's brother.
6. She Knows His Real Name
Some fans were unaware of Harris' given name, Adam Wiles, before Swift etched his initials into the sand during a tropical vacation. Using Harris' "real name" as a metaphor for private details of their relationship? That revenge song might as well have written itself.
On the other hand, the aforementioned vacay looked absolutely blissful -- and we'd be surprised if Swift didn't harvest a few lovely and heart-tugging lyrics from it.
