Taylor Swift and Travis Kelce are "incredibly happy together," a source tells PEOPLE. The pop star and the athlete will "have a break together" now that the NFL season is over.

In a recent interview with Laura Okmin of Westwood One Sports, Kelce opened up about a much different but perhaps equally massive stage he has been in. This was during the London leg of his girlfriend Taylor Swift 's "Eras Tour" concert when Kelce literally went up the stage in a cameo performance during the show.

Singer Taylor Swift played in sold-out stadiums around the globe on her recently completed Eras Tour, and boyfriend Travis Kelce was frequently on hand to lend his moral support. And Kelce even helped out at one of the concerts.
