Taylor Swift and Travis Kelce's lavish wedding celebrations have taken another luxurious turn, with the couple reportedly surprising guests with diamond-encrusted keepsakes ahead of their big day.

Before tying the knot on July 3 in New York City, the couple hosted an intimate rehearsal dinner at the Infosys Theater inside Madison Square Garden.

According to multiple reports, guests left the celebration carrying bespoke black velvet gift boxes featuring the couple's intertwined "TT" initials.

What's inside Taylor Swift and Travis Kelce's wedding gift boxes?

As celebrities departed the rehearsal dinner, several were photographed holding identical black velvet boxes embossed with Taylor Swift and Travis Kelce's initials joined by a heart.

According to Page Six, each box reportedly contained a diamond-encrusted champagne flute, specially designed as a keepsake to commemorate the wedding celebrations.

The presentation was just as luxurious as the gift itself. Each black velvet box featured the couple's "TT" monogram and was topped with a piece of frayed fabric printed with an image of the garden where Kelce proposed to Swift. The fabric wrapped around a commemorative card and was secured with an elegant silver wax seal, making the keepsake a personal tribute to the couple's engagement story.

Neither Swift nor Kelce has publicly confirmed the contents of the boxes, but the lavish party favors have quickly become one of the most talked-about details from their wedding weekend.
