McGregor was at the centre of attention as he was filmed gambling alongside South African rugby player Francois Hougaard with a big stack of cash in his hand while sipping on whiskey.

The Irishman appeared to enjoy trying his luck on the roulette wheel as he cuts a relaxed figure while spending heavily on the table.

One clip shows McGregor hand over a wad of notes and tells the clerk: ‘Give us another thousand chips but not for this, you can roll this.

He posted a number of clips on his Instagram and captioned it: ‘Gambling in Las Vegas, Nevada. One of life’s great pleasures’, with a heart sign.

Huge crowds eventually began to gather around McGregor who’s celebrity status makes him easily recognisable by supporters.

But on this occasion appears to love the attention and interacts with fans by waving a fistful of notes around and waving to those who cheer him on as he continues his gambling spree.

McGregor was also seen in Garcia’s dressing room after the defeat as he called on the American boxer to set up a rematch with Davis.

‘He’s 1-0 on you. Youse are the two biggest names in the division. I want to see it again,’ Mcgregor said.

‘I want to see it again now and I want to see it with no rehydration clause.

‘All respect to you. You are the future of this game. I am going to watch you all the way.’
