Conor McGregor is facing another legal spat after allegedly punching an Italian DJ in the face.

Francesco Facchinetti claims the UFC star broke his nose during a brawl at a party on Sunday morning.

The DJ has posted a video showing his injuries, claiming Conor thumped him after inviting him and his wife to a party.

Unprovoked, Conor reportedly threw the punch in front of witnesses.

"I took a punch for nothing," Francesco tells TMZ. "That punch could go to anyone. My friends, my wife, or other friends. That's why I decided to sue Conor McGregor because he is a violent and dangerous person…"

"Francesco flew back, fell on the table, and then on the ground," the DJ's wife tells the outlet. "The first thing that came to mind was, 'Are we kidding? Is it a show?' Then I was paralyzed.

"I turned around and saw that his friends were holding him against the wall because he wanted to continue beating Francesco. Then they took him away. I turned on the light and the guards turned them off. Francesco was bleeding. I wanted to help him and the guards chased us away."

Warning others to stay away from McGregor while he vacations in Italy, Facchinetti's wife adds, "He will stay in Italy until October 26th. If you see him stay away from him. Don't go near him and ask for autographs because he is an unstable and dangerous person."

Conor also hit the headlines for a red carpet scuffle at the MTV Video Music Awards in September, when he lunged at Machine Gun Kelly after the hitmaker reportedly refused to pose for a photo with the fighter.
