The highly anticipated wedding celebrations for Taylor Swift and Travis Kelce have officially begun, with the couple hosting an exclusive rehearsal dinner at New York City's iconic Madison Square Garden on Thursday evening . The event, which marks the start of what is expected to be one of the most extravagant celebrity weddings in recent memory, drew a dazzling array of A-list guests and set the stage for Friday's main celebration.

Among the notable arrivals were supermodel Gigi Hadid and her boyfriend, actor Bradley Cooper . Cooper was photographed looking sharp in a classic suit and vest, completing the formal look with sunglasses as he was seen entering an SUV outside the venue. Hadid, who is widely reported to be one of Swift's bridesmaids, kept a lower profile and was believed to be seated in the back of the vehicle . Longtime Swift friend Ashley Avignone was also spotted in the front passenger seat.

The guest list for the rehearsal dinner reportedly included around 100 of the couple's closest friends and family members . Attendees included Swift's trusted publicist Tree Paine, producer and frequent collaborator Jack Antonoff, childhood friend Abigail Anderson, and sports broadcaster Erin Andrews along with her husband, former NHL player Jarret Stoll . Travis Kelce's mother, Donna Kelce, was also seen arriving in New York ahead of the family celebration .

The rehearsal dinner comes amid intense speculation that Swift and Kelce may have already exchanged vows in a private ceremony prior to the public festivities. Multiple sources have suggested that the couple is already legally married, though neither Swift nor Kelce has confirmed or addressed these claims .

Meanwhile, Madison Square Garden has been undergoing a dramatic transformation for the main event, with red drapery and heightened security visible as final preparations continue . Friday's celebration is expected to host nearly 1,000 guests, with permits suggesting the extravaganza could last into the early morning hours . The couple also made headlines earlier this week with a reported $26 million donation distributed across 20 U.S. charities .

As the wedding weekend unfolds, all eyes remain on New York City, where Swift and Kelce are poised to celebrate what promises to be the entertainment event of the year.
