Justin Bieber Confronted By Fake Ivan Drago, Fight Me!

Fake Ivan Drago tried to pick a fight with Justin Bieber in front of Craig's last night -- showing up to the restaurant in FULL BOXING GEAR ... and we got the whole thing on video!!!

The wannabe Russian was SERIOUS about trying to fight Justin -- he's the same guy who showed up to Logan Paul's home a few weeks ago to challenge the YouTube star to a fight.

Remember, Logan actually AGREED and the two threw down right in Paul's back yard.

The fake-Drago is an aspiring social media star ... but it's clear he'll do ANYTHING for clout.

So with Justin trying to get an MMA fight with Tom Cruise. the imposter-Ivan planned to call out Bieber first at Craig's where he waited for JB at the front door, pounding his chest and talking trash.

Bieber blew him off ... so, he stuck around for a few hours waiting for a second crack at the pop star -- but that didn't pan out either.

Bieber clearly knows his worth (and his weight class) ... he could make MILLIONS if the Tom Cruise fight comes to fruition -- so why give out hands for free on the street?!

As for doppelganger-Drago ... he'll continue to seek out other famous people to fight.

We hear Mike Tyson's in town!!!
