Katy Perry are reportedly involved in a legal battle with an elderly veteran over the California home they made an offer on back in 2020.The dispute stems from the engaged couple’s attempt to buy a mansion in Montecito, California for $15million (£11.8million) from army veteran Carl Westcott, 83, three years ago.According to the Daily Mail, Westcott had moved into the home two months before the couple bought the estate. Westcott had allegedly signed a real estate contract to sell his home, but later claimed he was under the influence of opioids and painkillers after major back surgery.In court documents obtained by Daily Mail and The New York Post, Westcott “lacked the mental capacity to understand the nature and probable consequences of the contract”.A week after signing, Westcott said he began to feel “mentally clear again” after his surgery medication wore off.Westcott subsequently wrote an email to Berkshire Hathaway, the dual agent for the seller and buyer, saying that he did not want to go through with the sale.In response, Perry and Bloom’s representative presented Westcott with an increased financial offer – more than he paid for the home.
