Scottish singer/DJ Calvin Harris has opened up about his relationship with girlfriend, American singer/songwriter Taylor Swift.

During an interview with KISS FM UK, the 31-year-old DJ gushed about the 25-year-old Shake It Off singer.

"It's going absolutely fantastic," Harris said. "It's interesting, because obviously there's different things written about it every day and even if we don't do anything publicly for a while, someone will make something up."

Rita Ora's former boyfriend also talked about the weird reports surrounding their relationship.

"It does get more and more ridiculous, from me apparently being allergic to cats or Taylor and I are moving in together or we're getting married next week," he said. "It's a lot but you've just got to take it how it is which is that it's a news story that people read but it's just not real life."

"Then on the other hand, real life is happening," Harris added. "There's a whole bunch of times where we've been hanging out and nobody's clocked it. It's not like every single time we go out, we get a photograph taken of us."

Reports that Harris and Swift are dating started in March, and the two were pictured shopping in Nashville, dressed similarly.

Later, the two were spotted at a Kenny Chesney concert, getting cosy in the audience.

The couple made their relationship public when Swift kissed Harris during the Billboard Music Awards 2015, held at the MGM Grand Arena in Las Vegas on 17 May.

Harris revealed his bond with Swift is getting stronger, despite the media scrutiny.

"For me it could be a lot worse and I'd still be like insanely happy with her so I'm good with it," he explained.
