Katy Perry is embroiled in a contentious legal battle over a property the 32-year-old singer wants to buy. One of the nuns fighting the sale is Sister Rita Callanan, who says she’s struggling with ill-health.

Sister Callanan says the property is owned by the Order of the Immaculate Heart of the Blessed Virgin Mary, and along with another nun, Sister Catherine Rose Holzman, began a long fight to prevent Perry from buying it from the Royal Catholic Archbishop of Los Angeles, who also claims the convent is under its ownership. The Archbishop sold it to Perry for $14.5 million in July 2015.

According to the deal with the archdiocese, Perry would pay $10 million in cash and provide an alternative property for the house of prayer worth $4.5 million.

Sadly, Sister Holzman died in court last week, and Sister Callanan was left to continue the fight alone.

From the Daily MailStruggling with ill-health, including breast cancer, Sister Rita Callanan looks into her pantry for scraps of food and sees, yet again, only cereal.

Her bank balance is zero, her healthcare cheque has bounced on more than one occasion and she’s not sure who’s going to foot the bill for her next round of cancer treatment.

Now 80 years old, she scratches her head in bemusement as to how this has all happened. A few years ago, she had hundreds of thousands in the bank and was a paper millionaire.

As one of the few remaining sisters alive who belongs to the historic Order of the Immaculate Heart of the Blessed Virgin Mary in Los Angeles, her future was secure. Their historic convent sits in the uber-trendy Los Angeles suburb of Los Feliz and is today worth in excess of $10 million.

The report continues: Sister Callanan has vowed to keep on fighting [Perry] and asked the public to help the cause, setting up a GoFundMe page to help with legal costs.

She says: “On March 9th, 2018 we tragically lost Sister Catherine Rose, my beloved fellow IHM Sister and original organizer of this GoFundMe campaign. She was my cherished partner in this ongoing legal battle to keep our convent. It is now more important than ever to continue this fight and for our cause to prevail.”

Independent of who is right or wrong, amid such a complex legal battle, there’s the human cost. Sister Callanan is suffering from cancer and diabetes while multi-millionaire Perry told the nuns that she wants the stunning 22,000ft Mediterranean-inspired property so that she can “sip green tea and find herself.”
