All hell broke loose between Conor McGregor and Eddie Alvarez at the UFC 205 press conference

Chair fight!

If UFC 205 is anything like the presser, Saturday night's slate at Madison Square Garden should be bonkers.

UFC featherweight champion Conor McGregor showed up late to the presser, and UFC lightweight champ Eddie Alvarez had already exited the stage.

McGregor then danced across the stage and snatched Alvarez's belt and placed it in front of him. A clearly irked Alvarez grabbed his belt back, then pushed a chair into McGregor's. The featherweight champ then picked up the chair and tried to toss it at Alvarez before attempting to go at him.

Things got even more heated as Alvarez requested an apology for McGregor saying the lightweight champ's wife and kids won't recognize him after vowed to retire the champ.

We'll see what happens when the two champs step into the Octagon Saturday night.
