Katy Perry Killed a Nun?

If you think KATY PERRY and her music are harmless, then check this out:  A nun who was involved in a legal battle with Katy just DIED . . . right in the middle of a court hearing. 

The dispute started years ago, when the nuns sold the 8-acre property that used to be their convent to a businesswoman for $15.5 million.  The nuns themselves bought the property in the early '70s, so they felt they had a right to sell it. 

But the Archdiocese of Los Angeles claimed ownership, and THEY wanted to sell it to Katy for $14.5 million . . . and, of course, pocket the money from the sale. 

In addition to believing they were the rightful owners, the nuns also felt it would be a SIN to sell the property to Katy, because of her music and image.  So they went to court . . . and in 2016, they LOST.   

But there were still legal issues to iron out.  And during a court hearing this past Friday, an 89-year-old nun named Sister Catherine Ross Holzman collapsed and died, after experiencing chest pains. 

Katy still hasn't bought the property, because the Vatican needs to approve the sale.
