Nate Diaz clashed with Chase DeMoor and incited a messy scuffle at last night's Misfits Boxing event, which seemed to prompt the ugly street fight.
DeMoor, who starred in season two of Netflix's 'Too Hot to Handle', fought Stevie Knight at Misfits Boxing 6 in New Orleans on Friday.
But he lost his bout via disqualification after he landed a series of strikes on his downed opponent's head in an illegal move.

After the contest, DeMoor sat ringside and exchanged words with Diaz, who furiously launched a water bottle in his direction.
That triggered a brawl as DeMoor attempted to jump the barricade before picking up a chair.
Diaz taunted DeMoor as he managed to get away from the chaos. The Logan Paul lookalike, who was choked unconscious in a street fight, can be seen in the clip.
Following the event, the former UFC superstar was then filmed choking a person out in the streets in shocking scenes.

DeMoor was also present, with another video seemingly showing him fighting members of Diaz's entourage.
The video has since gone viral on social media, with UFC boss Dana White and Conor McGregor reacting to Diaz causing mayhem in New Orleans.
Watching the footage of Diaz, White said: "WHAT? He just kneed him to the stomach? Is that Logan Paul? He knocked him out? Whoever that, is he knocked him out! He choked him out! He's way too skinny - Logan Paul is a big motherf***er."

McGregor, who had two legendary battles with the Stockton slugger inside the Octagon, tweeted: "Hahaha Nate on a rampage tonight! Let’s go Nate! Hahaha."
In another tweet, he wrote: "Lovely little knee to the body hahahaa."
A third tweet reads: "I mince nate in the clinch these days. Actually anyone in the clinch. Minced."
Diaz, meanwhile, is set to return to action in August as he will make his professional boxing debut against Jake Paul.
