Colby Covington's support for President Trump has turned into an all-out bromance with POTUS' son ... 'cause Donald Trump Jr. says he considers the UFC star a good friend!!
Of course, the Trump family has been frequenting UFC events lately -- Trump Jr. and Eric were Covington's personal guests to his fight against Robbie Lawler in Aug. ... and they both attended UFC 244 last weekend with #45 himself.
As for Colby, he's been invited to 1600 Penn ... and even snapped a pic with Trump in the Oval Office.
So, when we saw DTJ out in NYC on Tuesday, we had to ask about the UFC megafight -- and if he'd ever consider walking a fighter out to the Octagon.
"I'd go out with Colby," Trump Jr. told us ... "He's become a good friend. There's a lot of great fighters out there but Colby's become a friend."
He might get his wish soon ... Colby is set to fight Kamaru Usman for the UFC welterweight championship at UFC 245 on Dec. 14 at the T-Mobile Arena in Vegas.
In fact, Colby put Don Jr.'s new book "Triggered" front and center at the official UFC 245 press conference last week to announce the fight. He also rocked his signature red MAGA hat.
