To push the talk even further, mentioned in a recent video uploaded by FightHype.com that he owns the Lamborghini he drives and the Rolls-Royce his son drives. Did he mention ownership as a jab towards McGregor? More than likely.

But is McGregor really renting the bright green Lamborghini Huracan he's been driving around in? After checking out his Instagram account, he's posted the car as far back as July 21 and he's also posted another Huracan with European license places, likely kept at his home in Ireland. I can't say for sure he's not renting the car while he's over here for the fight, but it's safe to say he's not shy from purchasing supercars and luxury cars (Conor McGregor's Car Collection). Also, with being in the United States for so long while he trains for the fight, it would make sense that he rented a supercar to cruise in for his stay in the states.
