Taylor Swift is pulling back the curtain on what it was like having Travis Kelce join her on the road with her during her "Eras" tour ... telling a hilarious story about a time where he confused an A-list actor's wife with his favorite director.
Swift sat down with Seth Meyers on 'Late Night' -- part of her press run for her new album "The Life of a Showgirl" -- and dished on what it was like watching Travis rage alongside celebs like Tom Cruise, Ashton Kutcher, Liam Hemsworth and more at one of her star-studded London shows last June.
