The Sister Act movies were wrong. Nuns can lose, and sometimes they lose to Katy Perry. The singer has been in a real-estate battle with a group of nuns over their former convent in Los Feliz, Los Angeles, which Perry offered a cool $14.5 million to purchase. The sisters turned her down, selling instead to Dana Hollister, who intended to turn it into a hotel. Problem is, the California Institute of the Sisters of the Most Holy and Immaculate Heart of the Blessed Virgin doesn’t actually own the property. The Catholic Church does, and Los Angeles Archbishop Jose H. Gomez decided to sell to Perry. After Perry made some fumbling attempts to win over the nuns — the former Christian rock star sang gospel songs for them; they said she “represents everything we don’t believe in†— the case went to court. Now, an L.A. superior court judge has ruled that the nuns’ attempts to sell to a separate buyer were “improper†and invalidated Hollister’s claim to the convent. The nuns may appeal the ruling, but barring that, Perry’s bid now only needs approval from the Vatican to complete the sale. Pope Francis, are you a Katy stan?
