... who's officially signed on to join Snoop Dogg's commentary team for the Jake Paul vs. Ben Askren fight!!

TMZ Sports has confirmed the "Saturday Night Live" star will be a part of the broadcast team for the very first Triller Fight Club 2021 event on April 17 at Mercedes-Benz Stadium.

We're told he'll be working the event alongside Snoop, Mario Lopez, supermodel Taylor Hill, and social media stars Dixie and Charli D’Amelio.

The play-by-play announcers are seasoned veterans when it comes to boxing -- Ray Flores, Al Bernstein and Mike Coppinger.

Snoop was the breakout star during the first Triller boxing event featuring Mike Tyson vs. Roy Jones Jr. -- he was in the broadcast booth calling the action and was HILARIOUS!

Remember, he was busting out church hymns as Jake put a hurtin' on Nate Robinson on the undercard.

So, add Pete Davidson to the mix!?! That's gonna be awesome.

As we previously reported, the Jake Paul vs. Ben Askren already has a stacked musical lineup featuring superstars like Justin Bieber, The Black Keys, Doja Cat, Saweetie, Diplo, Major Lazer and the debut of Snoop's new rap supergroup Mt. Westmore (which features Snoop, Ice Cube, Too $hort and E-40).

The main event will be an 8-round sanctioned professional boxing match featuring undefeated 24-year-old Jake Paul (2-0) going up against decorated MMA star Ben Askren, who's 36.

Askren has guaranteed victory over Jake -- saying he's never stepped in the ring against a REAL accomplished fighter.

Jake vows to wipe the floor with Askren -- saying the guy's striking ability is straight trash.
