It’s perhaps the most shared clip of Conor McGregor’s record-breaking UFC career.
For all of his brilliance inside the Octagon, it is his legendary personality that has made him the biggest star in the history of the sport.
And the image of him asking Jeremy Stephens ‘who the f*** is that guy?’, is one shared thousands of times on a daily basis across social media.
But despite being one of the most famous athletes on the planet, one of McGregor’s coaching staff has revealed there are some people that still leave him star struck.
The eyes of the world will be on the Notorious this weekend, as he makes his long awaited UFC return, facing off against Dustin Poirier on Fight Island.
Earlier this week however, even more were watching Jennifer Lopez, as she performed at Joe Biden ’s presidential inauguration.
And McGregor’s conditioning coach Colin Byrne has told the tale of when he first met the legendary recording artist, with his humble side clearly on show.
“We're in Vegas training for the second [Nate] Diaz fight in 2016,” Byrne told ESPN. “Conor gets a message from Cristiano Ronaldo, and he comes down to the gym. Conor said to him, ‘What are you doing in Las Vegas?’ Ronaldo says, ‘I'm going to Jennifer Lopez's birthday party tonight’.
“And then Conor just says jokingly, ‘Can we go?’ And Ronaldo says, ‘Sure, no problem’. And then he bounced and sent Conor a text to where it was.
“We get to the hotel, and inside Caesars Palace there's another private hotel, and it's where she has her suite.
He continued: “We get in the elevator, it goes up and the doors open. We walk out, and it's her apartment. On the wall, it says J.Lo in flowers. It's quiet. There's six of us in her house.
“We're like, what do we do now? We started walking. There were about eight people on an L-shaped sofa, and one of them was Jennifer Lopez. But there's no sign of Ronaldo -- and we weren't invited.
“Conor is going, ‘What do you think I should do?’ We were like, ‘You better go up and say hello’. Conor's like, ‘I don't know if she knows me’.
“He waves, and she's like, ‘Oh my god, Conor!’ She jumps up, grabs him by the hand and runs out with him toward the patio.
“On the patio, there's a whole dance thing going on. There's a deejay. Fat Joe is there. Ronaldo is out there. It was just absolutely brilliant. And she was such a pleasure. Conor got a selfie with her. I didn't.
"They had her band with a keyboard in the sitting room. We stayed for two songs. I would have stayed all night. It was one of the best experiences ever."
