It doesn’t matter how famous you are, when you see Taylor Swift, you immediately turn into the biggest fan boy or fan girl.

We are finding out how true that is after the pop icon showed up at Arrowhead Stadium on Sunday as the Chiefs got set to face the Chicago Bears. Kelce mentioned it to Patrick Mahomes a few days before, but the quarterback was still unsure if she was actually showing up.

Well, a new video is showing just how shocked Mahomes and the Chiefs staff were when they found out Swift was actually at Arrowhead.

“Oh s—! That’s Taylor Swift”

“What? Oh s—!”

“That’s who? Ohhhhhhhhh”

The singer stole the show as she stepped out to attend Sunday’s game.

Taylor Swift and Travis Kelce were spotted together, side-by-side, as they exited Arrowhead Stadium together after Sunday night’s Kansas City Chiefs game. Both did not display any signs of PDA as they walked but reportedly were very affectionate once they made it to dinner later that night.

At the time, Swift was rocking a Chiefs jacket tied around her waist, while Kelce appeared to don a denim set. No one knows if they changed before heading out to eat.

Swift is currently promoting the upcoming release of her next rerecorded album, 1989 (Taylor’s Version)
