Katy Perry is currently engaged in a legal battle with a group of nuns. The "Roar" singer is about to head to court against the sisters at Immaculate Heart of Mary after she purchased their convent situated in Los Angeles' Loz Feliz neighborhood. 

According to the Los Angeles Times, two of the five nuns, Sister Rita Callahan and Sister Catherine Rose, argue that the villa style hilltop convent, which offers views of downtown L.A. and the San Gabriel mountains, is legally theirs to sell. Sister Rita and Sister Catherine sold the property to restaurateur Dana Hollister for $15.5 million, which is an issue since Archbishop Jose Gomez is claiming that the property is his to sell. 

The L.A. Times reports that the nuns were able to sign the property over two weeks ago to Hollister before the archdiocese could complete its deal with Perry. 

Hollister, who has already moved into the property, told the L.A. Times that she might or might not turn the property into a boutique hotel — a move that residents of the neighborhood are reportedly against. 

The archdiocese is reportedly completing the paperwork on the sale to Perry, who has agreed to pay $14.5 million in cash. The singer reportedly got interested in the property three years ago and has wanted to make it her new home. 

Perry has previously met the sisters — who range in age from 77 to 88 — at the property in May. The "Teenage Dream" singer reportedly dressed conservatively and even gave an impromptu performance of "Oh Happy Day" for them and showed them a "Jesus" tattoo on her wrist. 

Sister Rita reportedly did an Internet research on the singer and said that she has found some videos of Perry, and said, "If it's all right to say, I wasn't happy with any of it." 

"We have given many years to this archdiocese to … put us under a bus and run over us, I'm sorry, it was just too much for me," she added.
