On March 6, 2015, Taylor Swift and Calvin Harris began dating after being introduced by Ellie Goulding at the ELLE UK Style Awards just a week before. On June 1, 2016, People reported the two split. "There was no drama," a source said. "Things just don't work out sometimes."

Unlike many other Hollywood couples before them, Taylor and Calvin never had to DTR in a TV interview or magazine cover story―instead they used social media to update the world about their relationship status. Here, a history of the duo's love story on Instagram.

FEBRUARY 25, 2015

"Cause we never go out of (Elle) style (awards)..... @samsmithworld"

This is from the night Taylor met Calvin Harris, mutual friend/matchmaker Ellie Goulding would reveal in an interview with The Sun. "Calvin is a really great mate and he's so fantastic, and Taylor is such a cool person who I love. I thought, 'They're both really awesome and both really tall. They'll be brilliant together.'" Tay was more focused on her pal Sam originally that evening.

Calvin may be taking the photo, but his own Instagrams from the same event (with Haim and Ellie Gouldingin one pic; Taylor's cats in another) confirm they're in the same place. Tabloids later give more detail about the party. "He surprised her and organized the whole night," a source told Us Weekly. "He even planned the menu!"

"She cooks too "

Calvin posts the first hint that he and Taylor are spending the Fourth of July together. This is also the first time Taylor herself appears in his feed. Two weeks later, Calvin will break his silence about the relationship to the press. "It's going absolutely fantastic," he tells KISS FM UK while doing an interview for his new single. "It's interesting, because obviously there's different things written about it every day and even if we don't do anything publicly for a while, someone will make something up. For me, it could be a lot worse, and I'd still be like insanely happy with her. So, I'm good with it." Of Taylor, "it's boxes I didn't even know existed, she ticks," he tells HITS Radio. "It's really ridiculous [all of her talents]...She's generally an incredible cook and human being."
