Sparks will start flying on July 2.

Ahead of Taylor Swift and Travis Kelce’s July 3 wedding, The Post can confirm the intimate celebration at Madison Square Garden the night prior is a rehearsal dinner.

A source revealed 100 close family and friends will be in attendance.

On Thursday, The Post confirmed the couple’s nuptials will be a multi-day event.

Swift and Kelce, both 36, will allegedly host between 1,000 and 2,000 people at MSG July 3.

The New York Times was the first to report the news.

Earlier this month, Page Six confirmed the Grammy winner and Kansas City Chiefs tight end’s wedding venue, with a source sharing, “Everyone’s been sworn to secrecy.”

Previously surfaced reports claimed Swift and Kelce were going to tie the knot in Rhode Island, where the pop star owns a large estate next to a swanky hotel.

At the time, rumors swirled alleging Swift cut a bride-to-be a hefty check to take the June 13 date from her at the waterfront venue.

However, in November, a source told Page Six the lovebirds wanted to go “all out” instead to accommodate more people.

Swift and Kelce have remained tight-lipped about details surrounding their special day, but reportedly locked down celebrity wedding planner Mark Seed to help.

“He can build something spectacular out of nothing,” a insider told Page Six. “He is renowned for never, ever talking about his clients.”

Swift allegedly invited guests over the phone, with A-listers such as Karlie Kloss, Zoë Kravitz, Ed Sheeran, Suki Waterhouse, the Haim sisters, Gigi Hadid and Selena Gomez — to name a few — seemingly scoring invites.

Meanwhile, Kelce’s Tight End University co-founder George Kittle recently addressed the upcoming event, playing coy about the location.

The San Francisco 49ers player and his wife, Claire, told “Entertainment Tonight” Wednesday that despite being invited, they don’t know where the ceremony is being held.

“I actually asked Travis last night and he laughed at me, so,” George, 32, shared.

The tight-end added, “I’m half expecting there to just be a jumbo jet on a runway and they put us on a plane somewhere.”

Last week, both Swift and Kelce seemingly celebrated their upcoming marriage with separate outings.

On June 17, a woman — who resembled Swift — was seen wearing white and surrounded by three girlfriends dressed in black on the balcony of her Rhode Island mansion.

Across the country, Kelce partied at Bird Streets Club in Los Angeles with brother Jason Kelce, comedian Druski and his former Kansas City Chiefs teammate Ross Travis.

The Kansas City Chiefs star proposed to the artist in August 2025 after two years of dating.
