Love him or hate him, Jackson Mahomes had the crowd buzzing at the Justin Bieber concert on Tuesday ... with fans rushing over to get a pic with the NFL superstar's brother.
The 21-year-old TikTok star showed up at Crypto.com Arena right before the "Peaches" singer took the stage for his second L.A. show this week ... and was immediately met with a swarm of concert-goers asking for a selfie.
We're told Jackson was happy to fulfil all the requests and was polite to all the fans before making his way to his floor seat.
