TIKTOK star Corey B threw CHALK in Paulie Malignaggi's face while the ex-boxing champion watched Lamar Odom's fight from ringside.
Malignaggi was a guest commentator as ex-NBA player Odom beat musician Aaron Carter in a bizarre celebrity boxing match.
But also ringside was social media personality Corey B, who has 6.8MILLION followers on TikTok.
The radio host, 33, sparked a recent war-of-words with retired fighter Malignaggi, 40.
But he escalated the rivalry by chucking chalk over the New Yorker, which led to a physical altercation between the two.
Malignaggi appeared to go along with the feud, as he reposted the clip on Instagram, and warned: "You're lucky you had bouncers saving you tonight."
The American was involved in a heated dispute with UFC superstar Conor McGregor, 32, in 2017 after an infamous sparring session.
Malignaggi stormed out of McGregor's camp prior to the Irishman's fight with Floyd Mayweather after footage of a disputed knockdown was leaked.
He went on to face the southpaw's training partner Artem Lobov, 34, in a 2019 bare-knuckle bout, losing on points.
Malignaggi has since remained out of the ring, but opened the door to another bare-knuckle fight.

He was also approached to fight YouTuber Jake Paul, 24, who is 3-0 in his career all by knockout.
Jake's brother Logan, 26, recently went the full eight round distance with boxing legend Floyd Mayweather, 44, in Miami.
And despite Malignaggi backing the farce fight between Odom, 41, and Carter, 33, he slammed fans for supporting the Paul brothers.
He told The Schmo: “You got these YouTubers making headway, making headlines fighting boxing matches, but they refuse to fight boxers.
"Because obviously if they fight boxers it’s not going to end well for them.
"So you’re kinda creating a niche, but it’s a really big nice because we live in the dumbest generation humanity has ever created.
"Because you have to be the dumbest generation to make this kinda thing popular.”
