Taylor Swift and Travis Kelce's extravagant wedding celebration, estimated to cost over $15 million, is underway at New York City's Madison Square Garden, drawing a constellation of stars from Hollywood and the NFL. The event, spanning multiple days, has commanded a significant presence, with 130 NYPD officers on duty and streets around the arena temporarily closed.

Guests, including celebrities like Gigi Hadid, Bradley Cooper, and Selena Gomez, arrived in black tie for the festivities. Swift's reported bridesmaid Gigi Hadid was seen en route to the event with her boyfriend Bradley Cooper. Other notable attendees included Swift's friend and producer Jack Antonoff, along with several NFL players.

Security measures were visibly in place, with guests undergoing searches and some opting to remove jackets in the reported 100-degree heat. Amidst the celebrity arrivals, Swifties and onlookers gathered outside the venue hoping to catch a glimpse of the event. Reports indicate a tiered system for guest entry, with some VIPs arriving via car while others passed through street-level security.

The guest list reflects a blend of entertainment and sports worlds. Jay-Z and his daughter Blue Ivy Carter, director Steven Spielberg, and former Kansas City Chiefs teammate Ross Travis were among those spotted in the city ahead of the celebration. San Francisco 49ers fullback Kyle Juszczyk arrived with his wife, Kristin, while Los Angeles Rams quarterback Matthew Stafford and his wife, Kelly, were seen in matching outfits. United States Women's National Soccer legend Abby Wambach attended with her wife, author Glennon Doyle.

Members of Swift and Kelce's professional circles were also present. Swift's publicist, Tree Paine, was among the early arrivals. Kelce's podcast producer, Brandon Border, and his fiancée, Lauren Winn, shared a car with Jake Chatzky, the senior director of social media for New Heights, and his pregnant wife Emily. Swift's childhood friend Abigail Anderson Berard also attended.

Kelce's uncle, Don, was seen in a tuxedo. Swift and Kelce reportedly hosted a 'rehearsal dinner' for 100 close friends on Thursday night. Unconfirmed reports suggest the couple may already be legally married, with the current event serving as a larger celebration.

Estimates for booking Madison Square Garden for two days range from $1.2 million to $1.6 million, with insurance costs around $10,000. Further expenses for lighting, sound, catering, decor, and labor are estimated between $10 million and $12 million. Permit fees could total at least $132,000, and taxpayer costs for police security and patrols are projected to exceed $1 million.

Reports indicate Swift and Kelce donated $26 million to 20 charities prior to the celebration, a figure that has led to speculation about its relation to the wedding's cost. The bride arrived for the initial event on Thursday in a heavily equipped Chevrolet Suburban. The venue was decorated with roses and adorned with dusty pink curtains, with reports suggesting custom enhancements within the arena.
