Katharine McPhee sang her support for Spencer Pratt as the former reality star continues his campaign for mayor of Los Angeles.

McPhee, 42, was recently filmed putting her own spin on Tina Turner's 1989 track "The Best" in support of Pratt, also 42, who officially announced his run for mayor in January.

"You're simply the best / Better than all the rest / Better than Karen Bass / And Nithya Raman," the American Idol alum sang, referring to incumbent Bass and City Councilmember Raman, who are also running for mayor.

"He's gonna fix this broken L.A.," she sang as her husband, David Foster, accompanied her on piano. At one point, McPhee encouraged the fundraiser crowd to join in, exclaiming, "Sing it with me!"

Pratt was seated behind McPhee during her performance, and could be seen nodding along to the music and tapping his foot as she sang.

McPhee and Foster hosted the fundraiser earlier this week at their home. One America News Network's Alicia Summers posted footage of the event to Instagram, captioning her post, "You know the tide is turning in California when @DavidFoster and @katharinefoster open their home and write a song for @SpencerPratt 👏"

Summers added, "La La Land is ready for a plot twist."

Pratt launched his campaign one year after he and his wife, Heidi Montag, lost the home they shared with sons Ryker, 3, and Gunner Stone, 8, in the Los Angeles fires last year.

The reality star vowed to "expose the system" in January, telling his supporters, "We're going into every dark corner of L.A. politics and disinfecting the city with our life and when we are done, L.A. is going to be camera ready again."

He has since surpassed Bass, 72, in campaign funding for the Los Angeles mayoral race, raising $539,616.85 since January, according to campaign records reviewed by PEOPLE last month. By comparison, Bass raised $494,734.76 for her campaign since January, according to The Los Angeles Times.

Pratt, a registered Republican, is running as an independent in the race. He recently compared his own political rise to that of former President Barack Obama.

“I have two awards from my community, President Obama actually didn’t even have awards when he was a community organizer,” Pratt, 42, told NBC Los Angeles’ Conan Nolan in a televised interview on Friday, May 8. “He was able to become a senator and then a president for eight years. So, I feel like him and I have the same experience.”

Pratt also attempted to shake his reality star past after appearing on The Hills, as well as Celebrity Big Brother and Marriage Boot Camp.

He told NBC Los Angeles he is a “community advocate,” his occupation listed on the June 2 ballot.

“I’m no longer a reality star,” he said. “It’s funny, I keep being called a reality star. I’m the only candidate living in reality, too.”

In fact, Pratt has ties to Foster, 76, thanks to his past on The Hills. Pratt is the former manager of The Hills' Brody Jenner, whose mother, Linda Thompson, was previously married to Foster before the pair split in 2005.

Pratt said last month that it was Foster who encouraged him to pursue on-camera opportunities with his first foray into reality television, The Princes of Malibu.

During an April 30 appearance on SiriusXM’s The Julia Cunningham Show, Pratt recalled creating The Princes of Malibu, which chronicled Jenner's life with his brother Brandon, as well as Thompson and Foster.

While Pratt made brief appearances on the show, he was more interested in a career acting and producing, he said. "I joke it's like The Matrix — I didn't realize I was taking the pill. And then once I was in, I was like, 'Too late,' " he recalled. "I didn't think about it, and that moment did change my life forever because nobody ever took me seriously again."

Foster, however, changed his perspective: "Then David Foster, he was like, 'You need to be the Simon Cowell of reality TV.' And I didn't even watch American Idol. I didn't even know who Simon Cowell was," Pratt said.

He added, "I was like, 'What? What does that mean? What are you talking about?' He's like, "Be the bad guy. Be the villain.' "

In a recent interview with Entertainment Tonight, Pratt even gave Foster a nickname, referring to him as "Fos Man."
