An elderly nun involved in a lawsuit with pop star Katy Perry over the sale of a convent in Los Angeles has died after collapsing during a court appearance.
Sister Catherine Rose Holzman, 89, had served the church "with dedication and love for many years," Archbishop Jose Gomez said in a statement on Saturday.
Holzman was a member of an order of elderly nuns involved in a dispute over the sale of their convent in the Los Feliz neighbourhood.
Hours before her death, Holzman spoke to television station KTTV , decrying a judge's ruling that cleared the way for the Archdiocese of Los Angeles to sell the convent to Perry.
"To Katy Perry, please stop," she said.
"It's not doing anyone any good except hurting a lot of people."
The singer sought to buy the three-hectare property and its Roman-villa style buildings for $US14.5 million.
Her efforts to buy the hilltop home were stymied when the nuns tried to sell the convent to a local entrepreneur to turn it into a boutique hotel, but a judge ruled in 2016 that the sale was invalid.
The Sisters of the Most Holy and Immaculate Heart of the Blessed Virgin Mary have owned the property for more than four decades but have not lived in the convent for several years.
