Taylor Swift bringing Travis Kelce onstage is the most Swiftian thing she could have done

• Travis Kelce made a surprise appearance onstage at Taylor Swift's Eras Tour show in London.
• It's the first time Swift has invited a boyfriend to share the spotlight during one of her concerts.
• The cameo recalls the 1989 World Tour — before Swift pulled back from the public eye.

Taylor Swift is no stranger to bringing guests onstage. But during her last show in London on The Eras Tour on Sunday, she had a very special one: Her boyfriend, Travis Kelce.
