Taylor Swift is getting protection befitting a head of state for her epic July 4 weekend wedding to Travis Kelce — in New York City’s Madison Square Garden — with beefed-up private security and a phalanx of police on hand, experts say.

The reigning princess of pop and her future NFL Hall-of-Fame fiancé will likely spend between $3 million and $5 million just to safeguard their two-day, celebrity-studded celebrations, former Secret Service agent Bill Gage told The Independent.

The couple hosted as many as 100 guests in the Garden on Thursday, and expects 1,000 on Friday, and the cost would cover weeks of advance work, as well as pairing up Swift’s personal security team with every MSG security worker and staffing a remote operations center to monitor potential threats, he said.

“This is like the equivalent of a presidential visit,” said Gage, who led the Secret Service tactical advance team for two State of the Union speeches by President Barack Obama.

A Swift spokesperson didn’t immediately return an inquiry from The Independent.

Swift, who’s been the target of several stalkers, reportedly spends $8 million annually on private security, up $2 million since last year’s assassination of conservative activist Charlie Kirk.

The increase pays for two additional security experts to ensure she’s “100 percent safe and comfortable all the time,” The U.S. Sun reported in November, citing an unnamed source.

Swift and Kelce are also concerned about protecting the privacy of their wedding ceremony, according to Star Magazine, which also cited an unidentified source.

“It’s a shame security has become such a big deal,” the source said. “But it is what it is, and Travis and Taylor are grateful they can cover the expense.”

Swift has a personal fortune estimated at $2 billion, while Kelce — the NFL’s eighth highest-paid player — is worth an estimated $47.3 million, according to Forbes.

In addition to private security, as many as 200 NYPD have been deployed around MSG, known as “The World’s Most famous Arena,” where a horde of fans turned out in 100-plus-degree heat Thursday and is expected to draw an even bigger contingent in near-equal swelter Friday, said Gage, now director of executive protection for the SafeHaven Security Group in Rogers, Arkansas.

Former NYPD Capt. Mark Novak told The Independent that a typical event at the Garden required the deployment of 40 officers, but that even if Friday’s crowd is relatively small, it would require two shifts of up to 70 officers each.

“I would suspect that the NYPD might pull from one or two boroughs for something like this,” said Novak, now president and chief operating officer of the Global Security Group in New York City. The city itself comprises five counties, colloquially known as “boroughs” — Manhattan, the Bronx, Brooklyn, Queens and Staten Island — and each borough has at least one, and in some cases two, “patrol boroughs” that oversee multiple police precincts each, with a total of about 33,000 cops.

But if 10,000 diehard Swfties show up, 200 cops would be needed to keep the scene under control, he said by way of example.

Novak noted that “probably everybody’s going to be on overtime,” after having already worked extra hours staffing the recent NBA Finals and the parade celebrating the Knicks’ historic championship and facing more during the looming crush of “America 250” Independence Day weekend events.

“I don’t think they could have picked a worse time to do this,” he said of the wedding date.

Novak, however, estimated a lower total cost for the couple’s private security, pegging it at $1 million to $2 million.

On Tuesday, The Independent witnessed entrances to the Garden being cordoned off along Seventh Avenue and blackout drapes hung along windows to the lobby looking out onto the plaza around the facility Tuesday. An MSG security guard said it and the vicinity around the Garden would all be closed until Monday, July 6.

Meanwhile, the Big Apple’s Fourth of July celebrations include eight New Year’s Eve-style ball drops in Times Square to mark midnight in every American time zone from 10 a.m. Friday (Guam and the Northern Mariana Islands) to 7 a.m. Saturday (American Samoa).

July 4 will also feature a Hudson River flotilla of more than 40 tall ships and a speech by Vice President JD Vance aboard the Navy’s amphibious assault ship USS Kearsarge.

That night, the 50th annual Macy’s July 4 fireworks show, with 85,000 shells fired as high as 1,000 feet from six barges in the Hudson and East rivers, as well as the Brooklyn Bridge, will take place with public viewing areas set up all around he festivities.

And Sunday will see a World Cup “Round of 16” soccer match at NYNJ Stadium, better known as MetLife Stadium, in nearby East Rutherford, New Jersey, with watch parties in Times Square and other locations and Penn Station, adjacent to MSG, a major hub for transit to and from that game.

Former New York City Comptroller John Liu, now a Democratic state senator from Queens, estimated the Swift/Kelce nuptials would cost the city “tens of millions” of dollars in police protection and cleanup costs.

That spending will be offset, however, by both the boost to the city’s economy and the “long-term benefit of being the place to have these marquee events,” said Liu, who punctuated his point by citing the titles of two Swift songs.

“And even if the short-term costs are significant, I think New Yorkers will shake it off,” he said. “And you know what? If Taylor and Travis decide to have their big day in New York City, we will all wish them the best day.”

City Hall didn’t immediately return an inquiry regarding the potential cost to taxpayers, even as speculation about the couple’s plans continued to run rampant.

Last week, a dozen New York City cops interviewed while on patrol around the Garden all said they doubted the wedding would take place inside, CNN reported.

“She’s a glamorous girl,” one officer reportedly said. “She wouldn’t get married here.”

A music industry insider also told Page Six that the marriage ceremony may have already taken place, a notion that’s reportedly shared by “many” in Swift’s orbit.

“I keep hearing the MSG rumors are all a fake out,” the industry insider said.

But Page Six and the New York Times also reported that a city permit application was filed for an MSG event to be attended by 100 people on Thursday, which an unidentified source described as a wedding rehearsal and dinner. The NYT said the Friday event would be attended by 1,000 guests.

Anton Kalaydjian, founder and CEO of Guardian Professional Security in Miami, Florida, told The Independent he’s handled security for several celebrity weddings, including those of singer Ariana Grande and real estate agent Dalton Gomez, and singer Alicia Keys and music producer Swizz Beatz.

All of those events were held in private and Kalaydjian said he would have advised Swift and Kelce to do the same.

“When it’s private, when it’s more family-oriented and friends-oriented, security is even greater, to be honest,” he said. “It’s much better for me to operate as a protector when it’s private.”

The former celebrity bodyguard said homes or estates allow the use of various techniques to keep a celebrity wedding secret, including bringing in “stage trees,” using speakers to play “cricket noises” and even hiring the best local paparazzi and sending them out of town on a wild goose chase.

Kalaydjian, who said he’s worked dozens of concerts for musician clients at Madison Square Garden, described the management there as “definitely good at what they do,” with about 150 security workers and interior spiral driveways to deliver artists to and from their upper-level dressing rooms.

“It’s one of the few venues that don’t allow vehicles to stay put,” he said. “Most of the time, you have to leave the building.”

But for Swift, “they would probably allow a vehicle to stay there, Kalaydjian said.

An MSG spokesperson didn’t respond to an inquiry from The Independent.

The only New York City wedding that’s “comparable” to the expected Swift-Kelce nuptials was the 1895 union of socialite Consuelo Vanderbilt to Charles Spencer-Churchill, Britain’s 9th Duke of Marlborough, said Manhattan’s official historian, Harold Holzer.

The event, he told The Independent, featured “multiday festivities and The New York Times devoted more than 2,500 words to coverage of the ceremony at Saint Thomas Church on Fifth Avenue at East 53rd Street and related events.

The front-page article that appeared in the paper’s Nov. 7, 1895, edition was topped by six headlines, including “SHE IS NOW A DUCHESS,” “GREAT CROWDS CHEER THE BRIDE” and “Thousands of Women Besiege the Young Woman’s Home and St. Thomas’s Church.”

“The wedding yesterday was, without exception, the most magnificent ever celebrated in this country, which was quite fitting, in view of the great wealth and social position of the bride and the high rank of the the bridegroom,” it said.

The superlatives continued: “The floral decorations in the church and the bride’s home were superb, the gowns of the women exquisite and costly, the music perhaps the finest ever rendered here upon such an occasion, and the bridal breakfast as dainty and as inviting as any ever prepared.”

Their match wasn’t made in heaven, however, and was instead forced on the 19-year-old railroad heiress by her mother Alva, as detailed in Consuelo’s 1953 memoir, The Glitter and the Gold.

“I considered I had a right to choose my own husband. These words, the bravest I have ever uttered, brought down a frightful storm of protest,” she wrote, according to an excerpt cited by professor Kathleen Burke of Britain’s Gresham College in a 2004 research paper.

The ill-fated marriage, which ended in divorce, later served as the inspiration for Season 3 of Julian Fellowes’ HBO series The Gilded Age, which is scheduled to return this fall after filming in upstate New York.

Despite the hoopla surrounding Taylor and Travis’ impending marriage, they wouldn’t be the first couple to say “I do” in the World’s Most Famous Arena.

That honor is held by the late funk-rock musician Sly Stone and his ex-wife, model and actress Kathy Silva, who got hitched between a warm-up set by soul singer Eddie Kendricks, formerly of The Temptations, and the main event concert by Sly and the Family Stone.

The June 5, 1974 ceremony was officiated onstage by Bishop B. R. Stewart of the Church of God in Christ in front of what The Times described at the time as a near-capacity crowd of almost 23,000 “yelling, screaming, stomping” fans.

In his 2023 memoir, Thank You (Falettinme Be Mice Elf Agin), Stone said the idea for his onstage wedding came up during a phone call with confidante and future best man Stephen Paley, a photographer who created the cover for Stone’s 1971 album There’s a Riot Goin’ On.

“Either me or Steve said that it should happen at Madison Square Garden and the other one laughed. But the seed had been planted,” according to Stone, who died last year at 82.

They spoke again the next day “and we grew the idea from a seed to a bud, from a bud to a flower,” Stone recalled. “I could do a gig, get paid, and get married at the same time. ‘Go, go, go,’ I told him. He went and went fast,” according to an excerpt posted online by Rolling Stone.

After the concert, Stone and Silva held their reception at the Waldorf-Astoria Hotel, where, Stone said, there was “drinking and dancing and smoking and joking, until the late hours and then the early hours, the kind of thing you remember only from the pictures you see afterward.”

Less than a decade later, the Garden was the scene of very different set of nuptials — the mass wedding of 2,075 couples who were members of the Rev. Sun Myung Moon’s controversial Unification Church.

Workers had scrambled to create an elaborate altar in the arena, laying 22,000 feet of white carpet, hanging colored drapes and international flags from the ceiling and setting up thousand of chairs, UPI reported at the time.

Outside, former members of the church protested against what one “deprogramed” ex-”Moonie” called the “cult-mind control movement.”

Moon presided over the July 1, 1982, mass wedding just weeks before he was sentenced in a downtown Manhattan courtroom to 18 months in prison for tax fraud and conspiracy involving $150,000 in income from bank accounts and securities.

On Jun 21, 1998, he returned to the Garden to preside over a ceremony in which more than 7,000 couples renewed their vows as part of an event that involved another 120 million couples taking part while watching a satellite TV broadcast, according to The Associated Press.
