Calvin Harris: February 2015 - May 2016

Taylor’s relationship with DJ and producer Calvin Harris lasted from early 2015 to 2016, making it one of her longest.

They split after 15 months due to “career pressures”, though public drama followed when she was revealed to have co-written This Is What You Came For.

Despite their post-breakup tensions, both later said there was no lasting animosity between them.
