What is Zero AIKansas City Chiefs tight end Travis Kelce's pregame meal? Cinnamon rolls, courtesy of Taylor Swift.

Former Super Bowl champion Bernie Kosar gave the inside scoop on what it's like to hang with the pop star ahead of a Chiefs game at Kelce's house, and on the dish she made ahead of the game.

Kosar joined Cleveland radio show "The Jen & Tim Show" and gave details on his experience hanging with Swift. Kosar was at Kelce's house prior to Kansas City's Week 7 contest against the Los Angeles Chargers for a "pregame meal."

He said he was at the home when Swift walked in by herself and while Kosar said he'd heard "she was awesome" to be around, the experience lived up to the hype.

"Getting a chance to meet her. I can't believe how even more awesome she was," Kosar said. "To be nice, to maybe me or the family, maybe that's one thing, but man, over a couple days, to see how genuine she was with everybody."

The Super Bowl 28 champion said Swift brought cinnamon rolls "for Travis." Even though he is more of a juicer, Kosar couldn't resist getting a bite of the baked goods.

"Hell, you go to try a little nibble of the cinnamon roll that Taylor did," Kosar said. "They were awesome."

It's no surprise that Swift cooked up sweet treats for her lover and others ahead of the Chiefs game. She's a known baker, even posting on Instagram in 2020 a picture of her now-famous cinnamon rolls.

Kelce has enjoyed success on the field with his love story unfolding in front of NFL and Swift fans this season. The Chiefs are 5-2 when Swift attends a game, while Kelce has 49 catches for 624 yards (89.1 yards per game) and two touchdowns in those contests. He most recently had five catches for 28 yards in Kansas City's win over the New England Patriots.
