Judge Miriam Walsh ordered McGregor to attend Blanchardstown District Court in Dublin or he would face arrest.
McGregor, 29, sent his business associate and business manager on two previous occasions but he today turned up wearing a green adidas tracksuit.
McGregor revealed he earned £123million for his fight with Floyd Mayweather and claimed the original payment for his £70 fine did not go through.
That riled Judge Walsh, who asked McGregor: “I have to ask you the question, how much do you earn?
“It may sound stupid but I have to ask – please don’t tell me that you earned €110m in one day.”
McGregor smiled and replied “€140m” before he was fined.
But Judge Walsh had earlier been annoyed by the fact Conor McGregor hadn’t turned up to court.
She told his lawyer Graham Kenny that McGregor could face arrest if he did not appear in person.
“This is absolute disrespect to the court,” she had said.
“I’m very annoyed with Mr McGregor in the same way I’m annoyed with any other defendant.”
McGregor hit back on Instagram when he posted a picture of his BMW car this afternoon.
Alongside the picture he wrote: “Getting charged in the super charge. #courthouse #relaxjudge.”
The comments amused his followers with one writing: “relax judge haha..judge just want a autograph and meet him in person.”
Another posted three laughing emojis and tweeted: “look at the hashtag relax judge.”
