Taylor Swift made a surprise appearance at fiancé Travis Kelce‘s Tight Ends & Friends concert on Tuesday night to sing her hit “Love Story” with Lainey Wilson.

The event, presented by Sports Illustrated and Reese’s, took place as part of Kelce’s Tight End University in Nashville, where the football player brings his fellow tight ends together for a three-day program of training and building community. Tight Ends & Friends also featured Dan + Shay, Chase Rice, Jon Pardi, Nate Smith, Mitchell Tenpenny, Brett Young and the War and Treaty.

Swift came out during Wilson’s set to screams from fans as the two proceeded to duet on “Love Story,” her 2008 hit that imagines a happier version of Shakespeare’s “Romeo & Juliet.” During the song’s bridge — “He knelt to the ground and pulled out a ring and said/ Marry me, Juliet, you’ll never have to be alone” — Swift notably flashed her own engagement ring from Kelce. Rumors have been rampantly swirling about their upcoming wedding, with reports speculating it could happen this month at Madison Square Garden or perhaps Swift’s Rhode Island home.

Swift has been out and about recently, sitting front row at Game 4 of the NBA Finals to cheer on the New York Knicks and promoting “I Knew It, I Knew You,” the song she wrote for “Toy Story 5.” She performed the track live for the first time at the movie’s premiere in Los Angeles earlier this month, and also sang “You’ve Got a Friend in Me” with Randy Newman.

“It means the world to me to be a small part of the universe of these films,” Swift told the audience. “‘Toy Story 5’ is my favorite of all the ‘Toy Storys.’ I’m so lucky I get to be a part of this.”
