The Grammy winner and the 1975 frontman have split, according to PEOPLE.

“She had fun with him, but it was always casual,“a source told the outlet.

“They are no longer romantically involved.”

The two, who never publicly confirmed their relationship, had quite the whirlwind romance.

This brief romance was not the first time the two have been romantically linked.

They first sparked dating rumors back in 2014, but Healy later denied it.

Healy and the 1975 are also currently on tour through September.

EW has reached out to a Swift rep for comment.
