The Joe Burrow and Kid Cudi bromance keeps growing stronger ... 'cause the Bengals QB just gifted his childhood idol with the jersey he wore in Sunday's AFC Championship Game!!
Cudi revealed that after Cincy's huge victory on Sunday ... he hit up Joey B and asked if he could have the game-worn threads.
"Ok. So after the Bengals win against the Chiefs, I hit Joe and congratulated him and asked if I could have his jersey," Cudi wrote on social media.
And Burrow wasted no time holding up on his promise -- shipping it right to the Cleveland native just 5 days after the Bengals secured their spot in the Super Bowl.
