Responding to the Joe Weller Fight

JJ responding about the drama.

The spat began after Weller won his first amateur YouTube boxing fight in August 2017 and KSI put himself forward as his next opponent. The two had many insulting exchanges on Twitter, and KSI created a diss track against Joe ("Two Birds One Stone") in August 2017 during the Sidemen Beef.

Upload Event

On 9 September 2017, KSI and Joe Weller attended the Upload event which was also live streamed to YouTube (on the Upload Event Channel). The drama began when both KSI and Weller "crashed" each others panels. When Joe came into JJ's panel, he was allowed on stage by security and the two had a brief pushing contest before being pulled apart.

The last show on the Sunday was a press conference officially annoucing the fight. The two traded insults at each other in front of young fans. At the end of the conference during a face off, Joe barged into KSI and a fight erupted when JJ threw security and one of Joe's friends to the floor trying to get to Joe. Security quickly pulled Joe off the stage. It is unknown if this was fabricated for dramatic effect.



On 11 September 2017, KSI made a video titled "Responding to the Joe Weller Fight". In the video KSI says that he will "kill" Joe in the boxing match and that he doesn't know what is coming. KSI also apologised for the inappropriate/insensitive comments he made about mental health during the feud.


On 18 September 2017, Joe made his own video where he responds to the drama. The match was officially happening.

On 3 February 2018, the fight happened. KSI clearly had the upperhand throughout the fight but Joe stood his ground, until the third round in which KSI was officially declared the winner by the referee.
