Something clearly went down between the The 1975 front man and Tay, because he's now taken a major swipe at the star AND her boyfriend Calvin Harris, despite previously admitting: "I wouldn't say no".
The Grammy Award winner was asked about his once rumoured romance with Tay Tay last year, saying it was a "flirtation" which didn't have a big impact on his life. Ouch.
The 26-year-old singer, who is clearly okay with talking about the singer to promote his latest record, went on to say he'd NEVER date Taylor and that he's not very good at relationships.
He said: "The reason I mention that is because if I had [properly] gone out with Taylor Swift, I would've been, 'F***ing hell, I am not being Taylor Swift's boyfriend.' You know, 'F**k. That.' That's also a man thing, a de-masculinating, emasculating thing."
