Longtime Hollywood conservative Kelsey Grammer called Spencer Pratt the only 'real option' for mayor of Los Angeles ahead of Tuesday night's jungle primary results.

Grammer spoke Tuesday morning as Pratt battles incumbent Democrat Karen Bass and insurgent leftist Nithya Raman in the primary, which could see the top two advance to a runoff in November.

'He's the only guy that's a real option,' Grammer told Fox News Digital of The Hills star.

While Pratt is a registered Republican, he's eschewed party labels during the mayoral campaign.

Frasier star Grammer has long been one of liberal Hollywood's conservative holdouts and expressed his deep skepticism of both Bass and Raman.

'We know what the rest is gonna do,' Grammer said of the other remaining candidates.

Grammer spoke last week about what his idea of conservatism leading to achieving the American dream means to him.

'If you come from a place of kindness and you come from a space of respect for others, all the other things will fall into place,' he said. 

'If you understand you gotta balance a checkbook, you gotta pay your bills, you gotta pay your taxes, there's a whole world of stuff you have to maintain. That's your ticket to freedom. That's your ticket to the American dream. It's hard work.' 

The Daily Mail has reached out to Pratt's campaign for comment. 

On Monday, Pratt saw praise from Donald Trump Jr on the President's son's podcast. 

Pratt has largely backed away from President Trump's endorsement but another member of the First Family praised him Monday night.

'Spencer Pratt seems like he has a lot of common sense in there,' Trump Jr said.

He then directly compared the trajectory of the former The Hills star to his father. 

'A reality TV star from two decades ago, and yet, you probably wouldn't have thought that a reality star from two decades ago would be the President of the United States, so,' he said.

'I think, again, his videos are great, they have no answer for them, other than, you know, having the leftist media shame this guy for speaking the truth and be right about basically everything. So I hope he wins, I hope he can change California.' 

Pratt, Raman and Bass will all face off in a jungle primary Tuesday, with the top two likely to move on to a November runoff should none of the three candidates get 50 percent of the vote.

A new poll by the California Post shows Pratt ahead in the race by a tiny margin, leading at 30.1 percent support. Bass is close behind at 29.5 percent, and Raman is in third place at 23.4 percent, according to the poll.

No candidate is likely to earn more than 50 percent of votes in the primary election on Tuesday, meaning a second runoff election between the top two candidates is on the horizon.

Beyond billionaire support, Pratt has also received endorsements from high-profile celebrities, notably including Joe Rogan and Paris Hilton.

In an episode of his podcast, Rogan said, 'I can't vote for you, but I'm rooting for you.' The influential celebrity moved from Los Angeles to Austin, Texas, in 2020 but added, 'If I lived in Los Angeles, no question whatsoever, I would vote for you.'

Hilton, the reality star and heiress to the hotel chain bearing her name, commented 'Spencer for Mayor' with a raised hands emoji on the candidate's Instagram campaign video showing the trailer he has been living in since the Palisades Fire destroyed his home.

Pratt's chances in the primary are certainly looking strong, but it is still anyone's game. The California Post poll that gave him a razor-thin lead of 0.6 percent over incumbent Mayor Bass has a margin of error of plus or minus 4.9 percent.

Even if Pratt is one of the two top candidates who makes it to a runoff election, the vast majority of Raman voters will likely flock to Bass, and vice versa.

If the independent challenger defies those odds, he will then face his biggest challenge in the general election, as Los Angeles tilts overwhelmingly blue.
