After 15 months of dating, Taylor Swift and Calvin Harris are history.

"This all happened last week," according to a source. "Taylor and Adam had no big blowout fight, but the romance just was not there anymore for them. Adam is the one that ended it. It was all done in a very mature fashion. Taylor is pretty upset but they are still in communication. Taylor was there for Adam with his accident and supportive."

The breakup comes on the heels of an auto accident Harris was involved in that caused him to cancel some scheduled concerts.

Swift and Harris met through mutual friend Ellie Goulding, who told 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.'"
