Forbesadded more fuel to the Katy Perry-Taylor Swift feud by ranking the "Roar" singer as the wealthiest female entertainer on the planet.

Perry landed at No. 3 on Forbes' list of the World's Highest-Paid Celebrities by earning $135 million over the past year. She came in second behind Manny Pacquiao (No. 2) with $160 million and Floyd Mayweather (No. 1) with $300 million. Swift came in at No. 8 with $80 million.

"[Katy] made about 60 percent of her $135 million abroad," Forbes Senior Editor Zack O'Malley Greenburg told ET. "That's partially because she's been touring."

But all the money in the world might not help her buy a former convent in the Hollywood Hills. According to the last remaining nuns, Katy performed "Oh Happy Day!" for them in an effort to win them over after they reportedly already sold the property to someone else.

"Our days have not been happy since then, I assure you," Sister Rita Callanan told the Today show.

While the nuns turned down Katy's $14.5 million cash bid, the Archdiocese of Los Angeles has expressed interest in selling the property to the singer. A judge is expected to settle the legal battle next month.
