David Foster pounded away at the keys while his wife, Katharine McPhee Foster, swayed through their backyard like an unpolished bridesmaid at a wedding reception, belting out a timely rendition of Tina Turner’s “Simply the Best” rewritten for Spencer Pratt’s mayoral campaign: “better than Karen Bass… and Nithya Raman.”

In footage posted to Instagram by One America News Network anchor Alicia Summers, Pratt is seen facing the audience as the Fosters performed on Monday night—representing a strangely poetic Hollywood moment for the candidate. Long before he was running for Mayor, “the Fos Man” (as Pratt refers to David Foster) encouraged the aspiring reality star to embrace his role as a villain—advice Pratt says helped turn him into one of the defining antagonists of 2000s television. During an appearance on the Joe Rogan Experience in April, Pratt recalled that Foster, who was previously married to Real Housewives of Beverly Hills star Yolanda Hadid, told him, “You got to be like Simon Cowell.” Years later, the Grammy-winning producer, whose daughters Erin and Sara Foster are behind the Netflix hit Nobody Wants This, was now helping legitimize Pratt’s candidacy for mayor of Los Angeles by hosting a fundraiser in his Brentwood Park backyard. Academy Award-winning producer Brian Grazer was also in attendance at the fundraiser, according to a photo reposted to Pratt’s personal instagram story. The Fosters and Grazer did not immediately respond to requests for comment, but Vanity Fair can confirm that the event took place.

“You know the tide is turning in California when David Foster and Katharine Foster open their home and write a song for Spencer Pratt,” wrote Summers, who attended the fundraiser. “La La Land is ready for a plot twist.”

Publicly backing Spencer Pratt, who has been labeled “MAGA” and “Trumpian” by his critics, still might carry the kind of reputational risk most Hollywood figures prefer to avoid. Just ask Grazer, who said “there was blowback” from Hollywood colleagues after his vote for President Donald Trump was publicized. Pratt has frequently said he hasn’t announced several of the people his administration would hire if he were elected because those people fear retaliation.

But the Fosters hosting a fundraiser for the reality-TV provocateur turned mayoral candidate suggests that stigma may be starting to erode. As Pratt’s campaign racks up viral attention and climbs in visibility, some figures in Los Angeles’s entertainment and donor circles appear increasingly comfortable treating his candidacy like a legitimate political and cultural force. Jeanie Buss, the minority owner of the Los Angeles Lakers, donated the maximum $1,800 to Pratt’s campaign. Malibu’s Most Wanted, Jamie Kennedy, is a Pratt supporter, frequently cheerleading his campaign on X. Social media influencer Jonathan Cheban, of Kardashian fame, says he will move back to Los Angeles if Spencer Pratt wins mayor. “I miss the LA energy, and only Spencer could bring it back,” Cheban said.
