Taylor Swift, Travis Kelce Sang Rock Duet at Rehearsal Dinner, Per Guests

Taylor Swift and Travis Kelce showed off their beautiful, magic love with a performance at their wedding celebration.

The night before the couple said “I Do” at Madison Square Garden in New York City July 3, the Grammy winner and Kansas City Chiefs tight end performed together at their star-studded rehearsal dinner, proving that they had music on their minds.

Indeed, Swift and Kelce, both 36, sang their favorite rock song together, two guests told NBC News while sharing details about the couple’s nuptials.

Although the “Opalite” singer did not take the stage herself, she still expressed how she’s enchanted by the NFL star through song, with the two attendees sharing that Swift sang a bit in her vows during the ceremony.

And while the guests didn’t reveal details about what was in the vows themselves, they said Swift and Kelce’s words left the hundreds of guests in tears. But the groom was particularily emotional, according to the attendees.

“You would think the bride would be the one crying more,” one of the guests told NBC News, “but it was actually Travis that was more emotional.”
