Katy Perry has topped fellow pop idol and rival Taylor Swift as the highest-earning woman in music.

Forbes reported that the singer raked in $135 million from her Prismatic World Tour and other ventures between June 2014 and June 2015.

Perry reportedly grossed more than $2 million per city while on tour.

"I am proud of my position as a boss, as a person that runs my own company," Perry said to Forbes for their Celebrity 100 cover story earlier this year. "I'm an entrepreneur. ... I don't want to shy away from it. I actually want to kind of grab it by its balls."

Swift, by comparison, made $80 million off her hit singles and massive 1989 World Tour, claiming the second spot on the list. Still, Forbes acknowledged that, due to the continued revenue from her tour, Swift will likely come out on top next year.

Perry and Swift have been quietly feuding in the media as of late. Tension between the former friends may have originally arisen from Perry allegedly stealing Swift's backup dancers a few years back.

Swift's hit single "Bad Blood" is rumored to be about Perry's betrayal and the collapse of their friendship.

In an interview with Vanity Fair, Swift did not comment on the rumors. However, she did make remarks about past friendships that went awry.

"I've trusted people before in friendships or relationships and have felt betrayed. I judge people based on their moral code; I think someone is nothing without a moral code," Swift said. "I don't care if you're talented or celebrated or successful or rich or popular, if you have no moral code. If you will betray your friend, if you will talk about them badly behind their back, if you will try to humiliate them or talk down to them, I have no interest in having a person like that in my life."

In the aftermath of Taylor Swift and Nicki Minaj's Twitter feud, Perry posted what was likely a subtle jab at Swift's "Bad Blood" video.

The band Fleetwood Mac, featuring Stevie Nicks and Christine McVie, came in third on the list. Lady Gaga and Beyoncé rounded out the top five.
