The most recent feud in Hollywood is pitting pop superstar Katy Perry against a group of Los Angeles-area nuns.

The "I Kissed a Girl" singer has been in talks to buy the property that was once a convent to the Sisters of the Immaculate Heart of Mary.

While Perry has made a $14.5 million deal with Archbishop Jose Gomez to turn the convent into her new home, the sisters aren't alright with Perry buying the property.

ET spoke with the last living nuns, who claim that the land is theirs to sell, and have already taken $15.5 million from local restauranteur Dana Hollister.

"The archbishop told us we would be taken care of the rest of our lives till the last sister dies," Sister Catherine Rose, who has called the convent in question home for over two and a half decades.

The archbishop, however, has argued that the sisters had no right to sell the property to Hollister.

The Sisters of the Immaculate Heart of Mary have stressed that it is Hollister who has their best interests at heart.

"When you have a resource like this.. it needs to find its way to be a part of the modern world and then it gets to live forever. and that's what they want," Hollister explained.

As for Perry, the nuns explained that, although she's "a very nice," "lovely" person, they didn't feel she was the right person to maintain the legacy of the convent.

"After she spoke [about] her lifestyle, and what we have been teaching for years and our older sisters have been teaching, and what we believe in, [she] just did not fit," explained Sister Catherine.

The Archdiocese of Los Angeles released a statement to ET, stressing that the well-being of the Sisters is their main concern. The statement reads, in part:

"The Archdiocese of Los Angeles has a longstanding commitment to the care and well-being of the Sisters of the Immaculate Heart of Mary. The stewardship of the Sisters and the Waverly Drive property were entrusted to the Archdiocese by the Holy See in 2005. The Sisters are not living on the property, which is vacant and deteriorating. The Sisters agreed that it was logical to consider a sale of the property. All proceeds from the sale will be dedicated to the care of the Sisters...

"... The Hollister transaction lacks the required approval from the Archdiocese and the Holy See, and does not provide a solution for the House of Prayer which is on the property. The Archdiocese continues to work with the Sisters to ensure that decisions concerning the sale of the property are made in their best interest. We want to make sure no one takes advantage of the Sisters."

Ultimately, the fate of the convent and who will be allowed to purchase the land is still up in air, and will be left to the courts to decide.
