Taylor Swift and Travis Kelce Attend Kansas City Chiefs Player George Karlaftis’ Greek Wedding

Karlaftis married Kaia Harris on Saturday, May 9, in Glyfada, Greece

Taylor Swift and Travis Kelce took their love to Greece.

Ahead of their own wedding, the engaged couple, both 36, attended Kelce’s Kansas City Chiefs teammate George Karlaftis’ nuptials in Glyfada, Greece, on Saturday, May 9, PEOPLE confirms.

The defensive end married his high school sweetheart, Kaia Harris, in a traditional Greek Orthodox ceremony that honored his culture at the luxury coastal resort One&Only Aesthesis. The three-day celebration also featured a welcome reception and farewell cookout.

Among the 220 guests were some of Karlaftis’ former and current teammates and coaches from both college and the Chiefs. When PEOPLE announced the couple’s marriage on Monday, May 11, many NFL stars congratulated them on Instagram, including Chiefs quarterback Patrick Mahomes and Chiefs owner Clark Hunt’s wife, Tavia Hunt.

“We have such cool friends, and the people we invited were just the best,” Karlaftis told PEOPLE exclusively. “Everyone got along, made new friends, and danced together. I couldn’t have asked for a better day and night, honestly.”

Earlier in the week, on Thursday, May 7, Swift and Kelce were spotted together in London on three separate occasions.

The pair were first photographed leaving Indian restaurant Gymkhana alongside British cinematographer Rina Yang, who has collaborated with Swift on multiple projects, including All Too Well: The Short Film, the Grammy Award-winning visual project released in 2021.
