A British barman has managed to blag his way backstage into yet another superfight, this time managing to sneak into the biggest fight in UFC history, Conor McGregor versus Khabib Nurmagomedov.

Oliver Regis previously posed as a part of Floyd Mayweather's security team in his bout with Conor McGregor last year, ending up ringside seats sat near boxing legend Mike Tyson and basketball star LeBron James.

This time the 33-year-old, who had purchased a $200 tickets for the fight, donned a flat cap so he wouldn't be recognised by security staff and made a daring break for ringside before the McGregor fight started.

He said: 'I put on a flat cap so the security staff couldn't see my bald head and managed to get through before the McGregor fight, so I was able to see the whole thing and the brawl afterwards.

'During the fights you are not allowed to walk through just in case you block people's view but in between the fights everyone gets up to get a drink or some food.

'I just went straight through and did not look back, I never even saw the seat I was given, it was brilliant.

'My mate was not as lucky, he got stopped by the security staff.'

The 33-year-old was also close to the post-fight melee which he described as 'crazy.'

He said: 'It was absolute carnage and an unbelievable thing to be part of.

'I was so close to everything, I saw one of Khabib's entourage get arrested and Conor's wife being escorted backstage when everything kicked off.

'It was crazy, seeing all the security staff involved and being right in the middle of it all, quite surreal.'

The bar manager also managed to sneak backstage at UFC 229 and get into the A-List star-studded VIP after party, by standing with self-help guru and multi-millionaire Tony Robbins entourage.

He added: 'To get backstage I followed Tony Robbins and his entourage and I managed to get counted as one of them right into the VIP section.

'It was fantastic, free drinks all night and I met Matt Damon and managed to get a picture with him, he was really nice and I told him I was a big fan of his movies.

'I saw Aaron Paul as well and had a quick chat with him, I'm a big Breaking Bad fan and showed him my Heisenberg tattoo, he said it was 'cool'.

But after leaving the VIP party, he did not get to meet his hero again, as McGregor did not turn up, but he still partied the night away until 7am.

The bar manager admits he is surprised he was able to get away with the same stunt twice.

He said: 'When I first got down near ringside I was worried a security guard had spotted me.

'But I managed to get away with it yet again, it just goes to show how easy it is to get ringside or backstage.

'Nobody ever really tries it but I just give it a go and I'm still going to try at future events!'

UFC 229 saw the undefeated Nurmagomedov attempt to defend his lightweight crown for the first time having beaten Al Iaquinta to lift the belt at UFC 223.

After his victory the truimphant Khabib then leapt over the cage, sparking a mass brawl.

Previously Mr Regis had bought a $2,500 ticket for the 'Fight of the Century' between boxing superstar Floyd Mayweather and McGregor, but was disappointed to find that it was in the nosebleeds at the top of T-Mobile Arena.

So instead of staying in his seat, the McGregor super-fan posed as part of Mayweather's security team to walk past other guards who failed to scan his ticket and ended up in the third row.

Oliver, from Stamford, Lincolnshire, said there were quite a few empty seats near the boxing ring and he couldn't believe his ploy was successful.

'I did feel a bit cheeky – but this was a once-in-a-lifetime chance,' he told

'I sat down in the third row and Mike Tyson then sat down behind me. LeBron James was on my row and I could see Leonardo DiCaprio.'

Much like this time the resourceful barman got pictures with Mayweather's father, Floyd Mayweather Sr, as well as football legend Vinnie Jones, Gerard Butler, Jeremy Piven, P Diddy, JLo, Demi Lovato, Eric Murphy, Jamie Foxx, Amir Khan and Chris Hemsworth.

After mingling with the A-listers, Oliver took a seat in the tenth row, right near Jones and LeBron James.

Oliver said that as the fight was broadcasted live on TV, friends started messaging him saying they saw him in the background.
