Travis Kelce and Patrick Mahomes

"The friendship started just because we’re very similar where we want to win," Mahomes said on TODAY of his longtime Kansas City Chiefs teammate, with whom he's won two Super Bowls. "But we like to enjoy life, too. We’ve kind of built this friendship of we’re gonna go out there and compete and we’re gonna enjoy it while we do."

Added Kelce, "You could tell the first day that Pat came into the building it was gonna be fun playing with him."

In addition to fierce rounds of ping-pong at Mahomes' house ("Travis has never beaten me"), the pals have gone on vacation and attended concerts together, and many of Kelce's childhood friends are now in Mahomes' regular circle.

And it has not gone unnoticed that the quarterback's wife, Brittany Mahomes, has been welcomed with open arms into Taylor Swift's squad, the ladies drawing eyes up to the visitors' suite with their own elaborate post-touchdown celebration.

"I need to talk to Travis because me and Travis don't even have a handshake yet," Mahomes quipped in an interview with sports radio station KCSP. "So I mean, they're ahead of the game on us."
