Did you know Patrick Mahomes is a great quarterback AND sick hype man?!?!
It's true -- 'cause the Kansas City Chiefs star took the stage at a Kane Brown show Thursday night ... and his antics had fans losing their minds!!!
Mahomes and his fiancee, Brittany Matthews, hit up the country concert in Kansas City for a date night one day before Patrick's 26th birthday ... and at one point during the evening, the signal-caller was pulled on stage.
And, it didn't take long for him to get the audience into the show ... because as soon as started pumping his arms, everyone went crazy!
The song choice, meanwhile, was perfect for Mahomes' entrance ... it was Brown and Chris Young's smash hit, "Famous Friends."
The lyrics? "When I go back home I've got some famous friends, yeah, I do."
Fitting, right?!
As for the rest of the night ... Mahomes and Matthews clearly seemed to enjoy it all, taking selfies and singing along to all the songs.
Mahomes, meanwhile, also got in a backstage pic with Brown at some point during the evening ... proving once again, it's REALLY good to be Patrick these days.
