The I Kissed A Girl hitmaker was in negotiations with the Archdiocese of Los Angeles to buy the former home of the Sisters of the Immaculate Heart of Mary in Los Feliz, but two former residents, Sisters Rita Callahan and Catherine Rose Holzman, objected.

They claimed it was their right to sell the eight-acre estate and they had already struck a deal with restaurateur Dana Hollister, who has moved in.

New legal documents obtained by the New York Times show an email the two Sisters wrote to the Archdiocese, which reads, "In selling to Katy Perry, we feel we are being forced to violate our canonical vows to the Catholic Church."

They also claim the Archdiocese is bullying them into accepting Perry's sale when they would prefer the property to go to Hollister.

Judge Robert H. O'Brien of the Superior Court in Los Angeles County is slated to decide who is the rightful seller of the convent at a hearing on 30 July (15).
