Patrick Mahomes Says Fame Hasn't Changed Travis Kelce, 'He's Just Been Himself'

Patrick Mahomes says dating a popstar and hosting "Saturday Night Live" hasn't changed Travis Kelce one bit ... telling reporters Wednesday his best bud has remained even keel despite all the newfound fame.

The Chiefs quarterback praised his tight end for not letting all the attention get to his head during his weekly meeting with media members ... explaining Kelce has "just been himself the whole time."

"He's still Travis Kelce," Mahomes said. "He still will walk through the stadium and treat every single person like they're his best friend. And he's going to be like that in the locker room every single day."

"It hasn't been any different."

Of course, Kelce's life has completely changed since he won his second Super Bowl last February. He drew a ton of laughs on "SNL," earned features in a bevy of new commercials ... and, as you already know, he got into a relationship with Taylor Swift.

But Mahomes was adamant that "Travis has always been Travis" throughout it all.

The 28-year-old signal-caller also had a bunch of nice things to say about Kelce's "SNL" appearance ... telling reporters he was super happy to watch Kelce live out a lifelong dream.
