Katy Perry is locked in a heated battle with an 84-year-old bedridden veteran over the sale of his mega-mansion, and only RadarOnline.com has exclusive photos of the $15 million Santa Barbara home, showing you exactly what they are fighting over.

The Fireworks singer, 38, and the aging 1-800-Flowers founder, Carl Westcott, are going head-to-head over the 8-bedroom, 11-bathroom house, which he claimed he was tricked into selling to the A-list couple in 2020 while on painkillers and recovering from a six-hour back surgery.

Westcott, who medical experts testified was incapacitated and suffering from early Alzheimer/dementia symptoms brought on by Huntington’s disease, which he was diagnosed with in 2015, said when the painkillers wore off, he changed his mind. When the vet approached Perry and her fiancé Orlando Bloom’s real estate agent about the mistake, he received a letter from their attorney revealing they were “not willing to walk away” and he was “obligated to complete the sale.”

The pop star has been dragged even deeper into the fight because she has been ordered to testify after claiming Westcott owes her $2.6 million related to the income she could have made if she had been able to rent out the bedridden businessman’s home. Perry and Orlando claimed they wanted to raise a family in the mansion — a reason why they aren’t giving up on taking over the property, despite Westcott’s family revealing this was the home he wanted to live out his last days in.

RadarOnline.com obtained the photos showcasing the abundant property to give readers an insight into what Perry and Westcott are battling over and why neither party is willing to walk away from the mansion — despite the dragged-out and highly publicized trial.

The 9,285-square-foot property — now estimated to be worth $17.5 million — sits on 2.48 acres in the elite Montecito, CA, neighborhood, which includes neighbors like Prince Harry and Meghan Markle, Oprah Winfrey, Ellen DeGeneres, and more.

Inside is a state-of-the-art kitchen, a butler’s pantry, and a massive wet bar for entertaining. A highlight of the home that’s meaningful to Westcott’s family is his office, where important business decisions went down. An honorable mention still hanging in the entrepreneur’s office today is the sign that reads “Carl kicks a–.”
