Appearing in court, the UFC fighter boasted to the judge that he earned £140million in one day as he was slapped with a speeding fine.
He was charged with exceeding the 100kmh limit on the N7 Naas Road at Rathcoole on March 31.
The sportsman, who claimed he earned £125million for one fight, has been given two months to pay the bill. Judge Miriam Walsh reacted: "I'm getting nothing but fingers from Mr McGregor".
However, shortly after the case was adjourned for the third time, reports surfaced confirming that the MMA star had finally arrived at the court after McGregor's solicitor had stated that he would contact his client regarding an urgent appearance. "It's an absolute disrespect to the court", she said.

On Thursday, Conor McGregor made a spectacle at an otherwise routine traffic court appearance, because he's Conor McGregor and he makes a spectacle pretty much everywhere he goes, whether it's at a local bar or a fight he wasn't even in.
Last time McGregor's case was before the same court on November 24, his "business manager" appeared in his place. If that is not paid within 28 days, the fine increases to €120 (£105).
