After penning a handful of breakup songs, Taylor Swift has reportedly moved on from ex-boyfriend Harry Styles for good.

According to Heat Magazine, via Metro, Swift, who has recently been romantically linked to Calvin Harris, realized that "Harry was never really more than a crush."

As a result, the "Blank Space" singer reportedly deleted the One Direction member's number from her phone, wanting to be in a "serious" relationship with the Scottish DJ-turned-underwear model.

"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," a source claimed.

With that being said, Swift and Harris were seen grocery shopping together at a Nashville supermarket and cuddling in the crowd at a Kenny Chesney concert just last month. At least, that's one witness tweeted. 

Last week, the blonde beauty was also spotted sitting on the EDM star's lap while watching her close pals Haim perform at the Troubadour nightclub in West Hollywood. The couple left the venue holding hands.

Meanwhile, the "I Knew You Were Trouble" hitmaker is scheduled to kick off her five-month "1989" world tour in May 2015, which will likely put a long distance between the two.

An insider revealed to Us Weekly, via HollywoodLife.com, that Swift has a plan to keep her romance with Harris going.

"She'll make time to see him [before she leaves," the insider said. "Tay has her private plane so she can fly anywhere -- or she can fly him to see her."
