MUMBAI: American pop singer- Katy Perry has been named by Forbes, the highest earning female musician, grossing $135 million (£88 million). The singer-songwriter beats rival- Taylor Swift by $55 million for the top spot, with Swift raking in $80 million (£52 million).

Perry, who turned 31 last month, released her last album ‘Prism’ in 2013. Although the “entrepreneur” made most of the year’s fortune through her ‘Prismatic World Tour’, her earnings were further boosted with endorsement deals such as CoverGirl, Coty and Claire’s.

Speaking to Forbes, the ‘Dark Horse’ hitmaker said, “I am proud of my position as a boss, as a person that runs my own company. I’m an entrepreneur. I don’t want to shy away from it. I actually want to kind of grab it by its balls.”

The business publication’s latest estimations showed British-American rock band- Fleetwood Mac’s female members- Stevie Nicks and Christine McVie in third position. McVie, the earliest and latest addition to the band, earned $59.5 million (£38.7 million), together with Nicks through the band’s ‘On With The Show’ tour.

Narrowly missing out on the top 3 is Lady Gaga. The ‘Poker Face’ singer ranked fourth, earning $59 million, having played 66 shows during the period. The singer also cashed in with her own Fame fragrance, along with Versace and Mac.

Beyonce follows Gaga in the list, with gross earnings of $54.5 million. The ‘Single Ladies’ singer, who was last year’s highest earner, managed to pull in over $100 million for 19 shows, with her husband Jay Z.

Britney Spears ($31 million) and Rihanna ($26 million) also made it to the list, at number 6 and 10, respectively, with Rihanna having played only nine dates in the considered period.

Forbes’ yearly estimation is based on industry information, as well as interviews with managers and artists who provide data for the earnings made during the period. The estimate is based on pretax income and is considered from 1 June 2014 to 1 June 2015.
