John Mayer is a Huge Fan of Girlfriend Katy Perry’s ‘Roar’

To no one’s surprise, John Mayer recently told Billboard that he’s a fan of “Roar,” the new single from girlfriend Katy Perry.

In fact, Mayer was a fan of the song before it reached the masses (and probably well before it leaked last weekend).

I remember hearing it for the first time, going like, ‘Wow what an interesting experience’ to hear something that you identify as massive before it’s massive,” he says in a video interview with Billboard. “I thought it was a really sweet, unforgettable sort of experience to hear someone’s work while they still have a very nascent sort of relationship with it.”

Mayer, who’s had an on-and-off (and now on) again romance with Perry, also opened up about the couple’s duet “Who You Love,” which leaked earlier this week. The track appears on Mayer’s upcoming album Paradise Valley.

The 35-year-old musician says the ballad is based on the idea of “I love you based on the fact that I’ve tried to run and I’m not running and I give up.”

I immediately thought about Katy and I was like, what a cool voice. What a cool artistic personality to have on. It was a really fun opportunity to write like, her answer to that,” he says of Perry’s contribution to the track.

“So you get these two sides to this relationship that are brutally honest but no less universal.”

Well, ain’t that sweet.
