After a years-long legal battle over the purchase of her $15 million mansion, Katy Perry – who appeared in a Los Angeles court via Zoom on Tuesday – has finally had her day in court. 

Carl Westcott – a U.S. Army veteran and the founder of 1-800-Flowers – filed a lawsuit in 2020 against Perry's business manager, Bernie Gudvi (who represented the "Firework" singer in the July 2020 purchase of the Santa Barbara-area mansion), after attempting to rescind the deal he made to sell his 8.9-acre estate to Perry for $15 million. 

Westcott had reportedly purchased the home two months earlier for roughly $11 million. At the time, Westcott sought a rescission of contract after claiming he "lacked capacity" to sign the transaction due to a recent surgery and brain disorder.

In November 2023, Judge Joseph Lipner ruled that Gudvi was entitled to the sale of the Montecito home purchased on Perry's behalf in 2020. On May 17, 2024, Perry took legal ownership after the deed was recorded. She is seeking up to $4.8 million in damages, including an additional $2 million for damages to the property, citing structural defects, deferred maintenance and lost rental income. 

The non-jury trial was split into two parts by the judge. The damages phase took place last year and the penalty phase kicked off last week. 

During her testimony on Tuesday, Perry detailed how the outcome of the lawsuit might impact her. 

"Do you have any financial stake of any kind in the outcome of this lawsuit?" Andrew J. Thomas, an attorney for the Westcott family, asked Perry.

"Yes," the singer, who appeared to be wearing a gray, button-down shirt, said. 

"Please tell us what that financial stake is," Thomas asked.

"Financial stake could be lost money, lawyer's fees, lost income for rental, and that's about it," she stated.

Earlier, Thomas asked if Perry stood to "gain money or anything else from the outcome of this litigation."

"Yes," she said. 

After Thomas asked Perry to elaborate further, the singer simply said, "Justice."

Ahead of her testimony, legal experts said Perry's testimony could prove to be a watershed moment in the case.

Craig Weiner, partner in Blank Rome's business litigation group, stressed that Perry's credibility will be tested during her testimony.

"The impact of Katy’s trial testimony will in large part rest on her credibility and ability to tell her side of the events in a clear and believable manner," Weiner told Fox News Digital. "As a litigant and celebrity, she should expect that the judge as trier of fact will pay close attention to the matter and possibly ask their own questions." 

"If she comes across as likable and truthful, her case will be helped. If she comes across as dislikable, not treating the tribunal with the proper respect, or not being truthful, she should expect that it will hurt her case."

According to LA real estate lawyer and litigator Eileen Kendall, founder of Kendall Law, the non-jury aspect of the trial, as well as Perry's demeanor during her "high-stakes" testimony, will have a major impact on the judge's decision. 

"Her testimony is high-stakes," Kendall told Fox News Digital. "Generally, jury trials pose high reputational and financial risk; bench trials provide more control, predictability, and privacy. A non-jury trial puts the decision in the hands of a judge, not a panel of everyday jurors. That means less chance of emotion driving the outcome."

Kendall added, "For Perry, that avoids the risk of jurors siding with the 85-year-old veteran simply out of sympathy. It also saves time, money, and media drama. But without a jury, she loses the possibility that some jurors might be star-struck or hesitant to rule against a celebrity."

Alice Jump, partner at Reavis Page Jump LLP, told Fox News Digital that Perry's celebrity "doesn't seem to be an advantage" in this particular case.

"She is testifying about actual damages, so it should be based on numbers, not glitz," Jump said. "If she starts talking about speculative damages, or she seems to be overreaching or greedy, her testimony might actually hurt her case."

The trial kicked off with a rocky start last week after Perry's legal team attempted to move the singer's testimony up and out of a scheduled order in the six-day trial. 

"That's outrageous… that she's only allowed to testify today," the judge said. "It doesn't reflect well on you, it doesn't reflect well on Ms. Hudson. It's not nice, it's not right."

Perry's lawyers noted that the musician preferred to go by her real name, Katheryn Hudson, and apologized for last-minute scheduling concerns, stating they were unaware of the singer's availability due to her demanding tour schedule.

Since the case was brought forward, a total of seven continuances were filed, six from the Westcott team. Lipner ruled that there would be no further continuances in the case.

While Perry has been ordered to take the stand, the Westcott family is also pushing for the singer's ex, Orlando Bloom, to testify. Bloom, who split from Perry earlier this year, was served a subpoena and named in the joint witness list. 

According to the Daily Mail, the judge said that he only needed the testimony of the contractors and questioned how Bloom's testimony would benefit. 

"Why do we need Mr. Bloom to (give testimony), other than making this a celebrity circus?" the judge said during a previous hearing.

Earlier this month, "Real Housewives of Dallas" alum Kameron Westcott said the family always wanted to settle. 

"We never, ever, ever even wanted to have to go to court," said Kameron, who is married to Carl's son, Court. "I mean, to be honest, we all always wanted to settle with her, and we never wanted to be in this position. Especially when my father-in-law has Huntington's disease and dementia. This is the last thing we want to do and deal with."

On Thursday, Westcott's son, Court Westcott, told Fox News Digital that the first day of the trial was challenging, but he has hope for his father.

"Emotionally, it was a draining day, but I'm also very optimistic and excited to finally get a chance to meet the person that has been absent for this trial," he said. "We're glad to have our day in court and we're looking forward to justice for my father."
