Conor McGregor gatecrashed Anthony Joshua's fight last night and it was pure chaos

Conor McGregor gatecrashed Anthony Joshua's bout against Robert Helenius at the O2 Arena and caused absolute chaos.

Joshua stopped Helenius with a devastating one-punch knockout in round seven to record his second straight victory following his defeats to Oleksandr Usyk.

UFC star McGregor was ringside as he cheered on the British fighter, where he could be seen hilariously shadowboxing.

And the pair also had a priceless exchange following the conclusion of the heavyweight showdown.

After Joshua beat Helenius, he left the ring and greeted his friends and family before making his way to McGregor.

The former world heavyweight champion took a sip of the Irishman's pint before embracing KSI, who was also ringside.

McGregor then got in the ring and called out KSI to a bareknuckle fight in a bizarre moment.

"I know your man KSI is in the crowd, yeah. He couldn’t box eggs if he worked in an egg boxing factory," he exclaimed. "So, if he wants to get in here, we’ll give him a fight - bare-knuckle if you want."

The YouTuber, who faces Tommy Fury in October, responded on social media, tweeting: "Lmao just seen this. Jake Paul must be crying that I’ve got Connor on my dick already and I didn’t even have to fight an mma fighter."

McGregor hasn't fought since July 2021 when he suffered a crushing defeat to Dustin Poirier at UFC 264.

But he's hoping to return before the year's out, revealing a December bout against Michael Chandler.

Asked when he's returning to the famed Octagon, he replied: "December - [Michael] Chandler, I have to do it. I’ve just got to grab him by the chest [and smack him]. That’s what I’ve got to do."

The 35-year-old added: "Chandler next in December and then [Justin] Gaethje, BMF and then we’ll do the Nate [Diaz] trilogy."

It's never a dull moment when the 'Notorious' is in town.
