A nun at the center of a court battle with pop singer Katy Perry collapsed and died in a Los Angeles court on Friday, Fox 11 reports. Sister Catherine Rose Holzman, 89, had been attending a post-judgment hearing as part of a lawsuit Perry and the Archdiocese of L.A. filed over an 8-acre convent in the Los Feliz area. Holzman and another nun who lived at the convent had tried to sell it to a local businesswoman, but a judge later ruled they didn’t have the legal right to sell the property. The businesswoman, Dana Hollister, was ordered to pay $5 million for interfering in Perry’s purchase of the property. On her way into the courthouse on Friday, Holzman reportedly pleaded with Perry to end her legal fight for the convent. “To Katy Perry, please stop. It’s not doing anyone any good except hurting a lot of people,” Holzman told Fox 11. The nuns had argued that their convent was under the control of the Vatican, not the L.A. Archdiocese.
