Sealed with a kiss.

Taylor Swift celebrated a successful second Eras Tour show in Buenos Aires, Argentina, by planting a smooch on boyfriend Travis Kelce, according to a video taken by a Swiftie in attendance.

Kelce — who had just watched the concert alongside Swift’s dad — was waiting for the “Anti-Hero” singer backstage at Estadio Monumental once the three-hour gig concluded.

Swift waved to adoring fans as she walked off stage before running into the a smiling Kelce’s arms to give him a big hug and kiss.

The pair remained in their romantic embrace and swayed back and forth for several seconds before separating just enough to continue walking into a private tent.
