Spencer Pratt's Mayoral Campaign

Spencer Pratt is trading campaign mode for island mode ... supporting wife Heidi Montag as she filmed her steamy new music video on location in Hawaii.

Heidi was serving serious beach-bombshell vibes while filming "Summer Love" ... posing in the surf and soaking up the tropical scenery like a total pro ... and Spencer wasn't far away.

The shoot likely made for a welcome distraction after Spencer's recent loss in the race to unseat L.A. Mayor Karen Bass.

Spencer Pratt's out of the Los Angeles mayor's race ... but he's not fading quietly into the abyss ... instead, he's threatening to take down one of the other candidates for mayor ... and he says he has a shocking recording that will make one of them resign.

The reality TV star makes the shocking claim in a new social media post ... a 3-minute clip where he vows his war against corrupt politicians in L.A. is only just beginning, even though his mayoral campaign is over.

Spencer says he has a recording he was saving for the general election, but now that he hasn't advanced ... he says he's going to wait to share it until after Nithya Raman or Karen Bass wins.

He claims the video shows one of the "exalted candidates doing and saying something that would make her resign in shame." He also hints it may have been recorded by one of their staff members.

Spencer Pratt's Los Angeles mayoral dream won't come true this year ... because he finished third in the primary election and won't advance to the runoff.

Mayor Karen Bass and City Councilwoman Nithya Raman won more of the vote than Pratt ... meaning the two will go head to head in the general election on November 3.

Now that 92.5% of the expected votes have been counted, Bass remains in the lead with 34.3% while Raman earned 28.5% of the vote compared to Pratt sitting at 25.8% ... according NBC.

President Trump is raising hell over Spencer Pratt's mayoral bid ... arguing the former reality TV star couldn't have legitimately fallen to third place.

POTUS unloaded on Truth Social Monday after new vote totals showed Pratt slipping out of runoff-advancing position in the Los Angeles mayoral race. Trump called the result impossible, blasted the city's election process and declared a "rigged" election.

Trump's frustration stems from Pratt's dramatic reversal in the days since Election Night.

As we previously reported, the former 'Hills' star spent much of the campaign emerging as one of Mayor Karen Bass' biggest challengers, even topping her in fundraising during parts of the race.

When the first wave of results rolled in, it looked like Pratt would be advancing to the runoff ... he was running second behind Bass. But as more ballots are counted and results slowly trickle in, City Councilmember Nithya Raman has surged past him, knocking Pratt into third place. The top two advance to November's runoff election.

Nithya Raman might just send Spencer Pratt packing ... from the mayoral race and the city.

Spencer promised to leave L.A. if he wasn't the next mayor, and he just fell to third place behind incumbent Karen Bass and Raman, a City Council member.

"The Hills" alum had been in second place since election night last Tuesday ... but Raman had been slowly closing the gap as results trickle in ... and now Spencer's dropped to third place.

Taylor Swift and Travis Kelce's MEGA wedding plans are finally revealed, Spencer Pratt waits impatiently for the count, Serena Williams tries to shake the retirement rust, and J Lo's a very proud mom. So, we gotta ask ...

Kym Whitley has some tough-love financial advice for Spencer Pratt ... and let's just say she's not exactly sympathetic to his explanation for blowing through millions during his reality TV glory days.

TMZ caught up with her Tuesday night at a Karen Bass election-night event at The Line Hotel in Koreatown -- and check out the video ... 'cause Kym doesn't hold back when we asked about Spencer spending $10M at the height of his fame.

She didn't hesitate before offering her take ... suggesting Spencer's current situation might've looked a whole lot different if he'd made a few different decisions back then.

Spencer Pratt is close to securing political success and advancing to the L.A. mayoral runoff election -- though he would still have one more challenge to face.

So far, the reality star has won 30.4% of the vote as of early Wednesday morning ... putting him in second place in the primary election behind his arch nemesis, Incumbent Mayor Karen Bass.

Bass has so far raked in 34.8% of the vote to put her in first place, earning her a spot in the general election on November 3 in Los Angeles. City Councilwoman Nithya Raman is currently in third place with 22.3% of the primary vote.

Spencer Pratt is firing back at folks who think he's bad with money ... and he's defending his much younger self for blowing through $10 million.

Spencer was on the "No Jumper" podcast when he took aim at critics bashing him for spending his own money back in the day ... saying every dollar he spent came from his "The Hills" paydays.

Spencer's running for Los Angeles mayor at 42 ... but when he was in his 20s, he says his life goals were much different ... get rich, get famous, and build an empire like Kim Kardashian.

Spencer says he never expected the reality TV gravy train to come to a screeching halt, so he wasn't treating the money like a once-in-a-lifetime opportunity.

Plus, as he points out, he wasn't spending anyone else's money but his own ... and definitely wasn't touching taxpayer dollars.

Jonathan Cheban is riding hard for Spencer Pratt's mayoral bid ... and things got so chaotic when TMZ ran into him Monday, it ended with a stranger flashing him in the middle of Beverly Hills.

Check out the video ... Kim Kardashian's longtime pal Jonathan -- better known as FoodGod -- didn't mince words Monday when we asked about Karen Bass' swipe earlier in the day at Pratt's reality TV roots. Cheban argues Spencer could breathe new life into Los Angeles and even claims he'd consider moving back to the city if Pratt somehow pulls off the upset.

But before he could fully make his case, a passerby jumped into the conversation with an unrelated rant ... and that's when the interview took a sharp left turn.

President Trump says he is heading back to New York to watch the Knicks, but how will MSG react?? Plus, Spencer Pratt's mayoral fate will soon be decided and the controversy over Kevin Hart's roast continues. So we gotta ask ...

Spencer Pratt's allegation about Mayor Karen Bass breaking the law in one of her campaign videos could lead to a police investigation ... TMZ has learned.

Josué "Josh" Marcus with the City Clerk's Office tells TMZ they've seen Spencer's official complaint, and ... "After review, our practice is to refer these allegations to the Los Angeles Police Department for further investigation, which we will do for this and any new allegations."

Basically, the City Clerk's Office is putting the ball in LAPD's court ... asking the city's police force to decide whether the city's mayor committed electioneering in her latest campaign vid.

Spencer Pratt's mayoral campaign just scored a shocking endorsement -- from someone who once called voting for him "stupidity" ... his own sister, Stephanie Pratt.

Stephanie's now she's doing a full-on political U-turn ... admitted she was the first person telling voters they were idiots if they backed her brother, before confessing, "Wow, was I wrong."

She told Vanity Fair Spencer's been grinding nonstop since the L.A. fires -- claiming "he has spent every day since the fires, finding the facts, the mistakes, the negligence and uncovering the truth that they never wanted us to know."

Spencer Pratt's run for L.A. mayor has people throwing around Donald Trump political comparisons -- but Spencer's making it crystal clear ... he's not riding that wave.

In a new profile, Spencer went all-in defending his love of Mexican culture -- noting he's probably eaten more Mexican food than any white guy in Los Angeles, claiming he's been hitting it around three times a week for the last decade.

The reality star turned mayor hopeful made the comments to Vanity Fair while weighing in on federal immigration enforcement -- saying he doesn't support ICE or the raids happening across the city.

11:23 AM PT -- Karen Bass's campaign spokesperson, Alex Stack, tells TMZ ... “Spencer is just mad that his supporters are A.I. cartoons and we have real Angelenos. We follow the rules.”

Spencer Pratt is escalating his war with Karen Bass ... accusing the Los Angeles mayor of illegally electioneering near ballot boxes.

The mayoral candidate alleges Bass crossed a legal line by campaigning too close to ballot drop boxes during early voting in L.A. ... accusing her of soliciting votes and promoting her campaign within 100 feet of polling locations.

According to the complaint, Bass allegedly documented the whole thing herself on social media ... posting videos and photos showing campaign signs, ballot drop-offs and supporters encouraging people to vote for her.
