The “Blank Space” hitmaker split from the Scottish DJ in June after over a year of dating, the two are back on good terms.
Sources told tmz.com, Swift and Harris began exchanging text messages shortly after her brief romance with Tom Hiddleston ended earlier this month, though it is unclear who got in contact first.
However, the insiders insist the pair will not be rekindling their relationship, and they have not spoken on the phone or met up in person.
The 32-year-old producer recently admitted he found it “very difficult” having his break-up with Taylor, 27, play out in public.
“It’s very difficult when something I consider so personal plays out very publicly. The aftermath of the relationship was way more heavily publicised than the relationship itself. When we were together, we were very careful for it not to be a media circus. She respected my feelings in that sense,” he added.
