If Taylor Swift is mining her relationship with Calvin Harris for material, we're in for some feel-good songs. Speaking with Kiss FM UK, Harris said that his relationship with Swift is "going absolutely fantastic." But here's the thing about dating Taylor Swift: even rumors invented about your relationship can become cat-related. "It gets more and more ridiculous, you know? Whether I'm allergic to cats or [I'm] moving in, and we're getting married next week," he said. Harris did say, however, that the two can, sometimes, evade the public's eye. "For me, it could be a lot worse, and I would still be insanely happy with her, so I'm good with it," he said. Whether that happiness will translate into a musical collaboration is still up in the air. Asked about the potential, Harris said he didn't know. You can listen to the full interview here. Meanwhile, Swift's friend squad keeps growing by the day. The newest additions: Ian McKellen and Patrick Stewart.
