Calvin Harris 'insanely happy' with girlfriend Taylor Swift

Calvin Harris gushed about girlfriend Taylor Swift in a new interview Friday.

The 31-year-old Scottish DJ discussed the 25-year-old American singer with Kiss Breakfast on U.K. radio station Kiss FM. Harris and Swift have been dating since the spring, and the EDM producer said he couldn't be happier with the pop star.

"It's going absolutely fantastic," he said. "It's interesting, because obviously there's a different thing written about it every day ... For me, [the public scrutiny] could be a lot worse and I'd still be, like, insanely happy with her. So, I'm good with it."

Harris dismissed rumors he and Swift plan on getting engaged, and said he isn't sure the pair will ever collaborate musically. The DJ reportedly praised the singer to Hits Radio U.K. the same day, saying, "It's boxes I didn't even know existed, she ticks."

Harris and Swift were first linked in late March, and spotted holding hands the next week. The couple have gone increasingly public with their relationship, and are openly seen out and about, in addition to posts on social media.

Harris released his fourth studio album, Motion, in October 2014, and debuted new single "How Deep is Your Love" on Friday. Swift released her fifth record, 1989, the same month, and is currently on the North American leg of her accompanying tour.
