Nate Diaz clearly ain't sweatin' his criminal case down in Louisiana ... the former UFC star actually had a laugh about it all with Jake Paul on Tuesday.
Paul was the one who brought up the choke-out incident to Diaz during a news conference to hype up their August boxing match ... wondering if the MMA fighter thought he was scrapping with his brother, Logan Paul, when he choked out a guy on Bourbon St. during an April 22 melee.
Diaz smiled and then pretended to truly believe it was Logan who he put to sleep on the popular New Orleans roadway.
