Taylor Swift had a surprise for fans attending her Eras Tour at London’s Wembley Stadium on Sunday: her boyfriend and tight end for the Super Bowl-winning Kansas City Chiefs, Travis Kelce. Dressed in a tuxedo with a tailcoat and top hat, Kelce joined Swift on stage for a transitional sketch that leads into the song “I Can Do It With a Broken Heart.” In fan videos, he’s seen carrying Swift, urging her into a costume change. He fanned and powdered her face as part of the act. The billion-dollar Eras Tour is meant to be a career retrospective, with Swift performing more than 40 tracks reflecting 17 years of recorded music.
