March 11: A nun embroiled in a property dispute with singer Katy Perry collapsed and died during a court hearing on Friday, US media report.
Sister Catherine Rose Holzman was 89.
She was one of two nuns locked in a legal battle with Perry and the Los Angeles Archdiocese over a former convent in the city.

Perry agreed to buy the property for $14.5m (£10.4m) in 2015, but the deal turned sour when the former residents objected.
Sister Catherine Rose and Sister Rita Callanan said they were uncomfortable handing the convent and its eight surrounding acres over to the star, whose sometimes provocative hits include I Kissed A Girl and Ur So Gay.
Perry reportedly visited the nuns to win them over, and is said to have shown them her tattoo of Jesus and sung a hymn for them. But the pair remained unconvinced.
"I found her videos," Sister Rita Callanan told the Los Angeles Times. "I wasn't happy with any of it."
The nuns instead sold the residence to local restaurant owner Dana Hollister, without the approval of their Archdiocese.
