how's one to know?

The personal event included the couple’s family and celebrity friends, including Lena Dunham, Jack Antonoff, Erin Andrews, Charissa Thompson, Greg Olsen, and Aric Jones, who were spotted arriving at the venue around 6 p.m. on July 2. The A-listers brought glam to the celebration, sporting jewel-toned and sequined dresses.

Selena Gomez shared a selfie from the car, while Abigail Anderson was also spotted en route to the dinner.

Jones is a longtime friend of Kelce’s, telling PEOPLE in an earlier interview that he met Kelce in Cleveland Heights, Ohio when Kelce was about 6 and Jones was around 4.

Anderson and Swift are also longtime best friends, having met in English class on the first day of freshman year at Hendersonville High School in Tennessee over 20 years ago. Anderson is the inspiration, in part, for Swift’s hit song “Fifteen.”

The second insider says that at the wedding, which took place on Friday, July 3, at Madison Square Garden, “the food was endless.”

“There were so many stations and options,” the source says, adding that there were “lots of doughnuts around where the games were.” The party featured numerous games, with winners getting raffle tickets for the chance to win items like designer bags, watches and a 1970 Chevrolet Chevelle, the same car that Kelce drove off in with Swift after her first Chiefs game in September 2023.

Another insider previously told PEOPLE that the reception included stations with Italian offerings like pasta in a parmesan wheel, along with sushi, steak, burgers and fries and seafood. There were also “bars everywhere,” the source said.

TMZ reported that the singer and Chiefs tight end bypassed a traditional wedding cake, instead opting for a massive dessert table topped with about 30 different cakes, each of which featured a unique 3D figure of the couple. The outlet said the dessert offerings also included other sweet treats.

A source told PEOPLE exclusively that the dessert table included items like pop tarts, cookies and pastries and was “a focal point” of the festivities.

The fun-filled celebration followed the couple officially getting married, as Swift’s rep confirmed to PEOPLE. The news was also announced on jumbotrons outside the arena that said: “JUST&T MARRIED!”

An insider told PEOPLE that the couple read their vows, which were about 20 minutes each, from gold books. The source said the arena “looked like a forest,” with ferns, trees and seats covered in white.

A-listers were seen flocking to the event, which included an estimated 1,000 guests, including Dakota Johnson, Mariska Hargitay and Peter Hermann, Gigi Hadid and Bradley Cooper, Ed Sheeran and Cherry Seaborn, the Haim sisters, The Chicks, Brad Paisley and Kimberly Williams Paisley, Hugh Grant, Zoë Kravitz and more.
