Taylor Swift and Travis Kelce hosted an intimate rehearsal dinner on Thursday night at the Infosys Theater within Madison Square Garden, gifting approximately 100 guests diamond-encrusted champagne flutes.

The keepsakes were presented in black velvet boxes bearing the couple's initials. Inside, guests found a large champagne flute adorned with real diamonds. The boxes also contained a commemorative card, featuring an image of the garden from the couple's engagement photos, fastened with a silver wax seal.

Attendees at the exclusive event included Gigi Hadid, Bradley Cooper, Selena Gomez, Lena Dunham, Jack Antonoff and his sister Rachel, Ashley Avignone, sports reporter Erin Andrews and her husband Jarret Stoll, Swift's publicist Tree Paine, and childhood friend Abigail Anderson. Kelce's manager Amanda Santa, his friend Reggie "Regrunt" King and his wife Sarah, and commentator Charissa Thompson were also present.

The rehearsal dinner preceded a larger wedding celebration planned for 1,000 guests on Friday. The decor for the wedding reportedly featured a garden theme, with large floral arrangements in peach and pink tones. Areas within the arena were transformed to resemble a forest, complete with trees and grass-like carpeting.

The color scheme for the event was dominated by dark green and pink, accented with white round couches, high-top tables, bars, and a prominent white staircase.

Sources indicated that Swift and Kelce, who began dating two years ago and became engaged last year, had already privately married ahead of the larger ceremony.

Expected guests for the main wedding celebration included Ed Sheeran, the Haim sisters, Sombr, Suki Waterhouse, Cara Delevingne, Mariska Hargitay, and Kansas City Chiefs coach Andy Reid. "Only Murders in the Building" actress Selena Gomez was rumored to be a bridesmaid.

The wedding festivities were scheduled to begin with a cocktail hour on the sixth-floor concourse around 4 p.m. ET, followed by the ceremony on the arena floor at 5:30 p.m. ET. The reception was expected to continue until 4:00 a.m. Saturday.
