The Chiefs star tight end, 34, even remarked about his girlfriend, music icon Taylor Swift, in the process.
A clip on TikTok went viral of a mustached Kelce surprising a group of Chiefs fans at the team’s training camp facility on Sunday.
The three-time Super Bowl champion was spotted approaching the fans, and asked them, “What are you guys doing in my hallway?”
One of the fans then told Kelce, “You guys took my wife’s breath away, literally she just almost died.”
The woman, who was sporting a camo hat, laughed after her husband’s remark.
Kelce quickly replied, saying, “[It’s the] Taylor Swift effect.”
The group laughed as the video came to an end.
The caption of the post read, “Unbelievable day at @Chiefs friends and family day. Thank you for the time.”
In a follow-up post, Kelce posed for a snap with the same woman.
The 34-year-old smiled as he rocked a gray T-shirt and red athletic shorts in the photo.
The group caught Kelce and the Chiefs as they are currently in training camp.
The NFL star’s stardom has skyrocketed since he began his relationship with Swift last summer.
Kelce’s New Heights podcast is one of the most popular podcasts in the United States.
He co-hosts the podcast with his brother and NFL icon Jason Kelce.
Last season, Swift attended numerous Chiefs games including their Super Bowl overtime win in February.
Kelce has returned the favor and has appeared at multiple Eras Tour shows during the offseason.
In June, he performed on stage at Swift’s concert in London, England.
Kelce and the Chiefs will be preparing for their first preseason game when they play the Jacksonville Jaguars on August 10.
Kansas City will face the Baltimore Ravens in the NFL’s first regular-season game on September 5.
Kelce and the Chiefs will be eyeing the league’s first-ever Super Bowl three-peat.
