Calvin Harris

Three years after the end of their romance, Swift has put Styles into the past. Source:

Taylor once thought she loved Harry, but since getting to know Calvin [Harris], she’s realised that Harry was never really more than a crush. The relationship was not nearly as serious as she thought it was at the time. Taylor was more than happy to delete Harry’s number. Calvin’s made her realize that boys like Harry are toxic for her and given her the confidence to cut him out of her life for good. She’s determined to show Calvin she’s serious about him and wants him to feel as secure as she does.
