When 32-year-old Harris first released the song in April, Swift shared some very supportive posts, promoting the song on her own social media. Taylor, 26, also supported Harris when he performed the song with Rihanna at the Coachella Music Festival.
However, the posts have since been removed from her social media.
Swift appears to have wasted very little time moving on from the 32-year-old DJ, after she was snapped kissing English actor Tom Hiddleston.
The couple, who were caught kissing by photographers on Rhode Island, have already had their couple name chosen by the Internet. Social media platform Tumblr asked their followers to vote for their favourite nickname for the couple. The result? Swiddles.
