Conor McGregor and Artem Lobov
There was a time not too long ago when McGregor and Lobov were inseparable. The pair became very close during their time as training partners at SBG Ireland. Lobov helped the Irishman to prepare for his biggest matches. Meanwhile, McGregor’s influence was key in helping Lobov earn a coveted spot on the UFC roster (via MMA Fighting).
In the end, money came between them as they fell out over McGregor’s whiskey brand. The Irishman sold his Proper 12 company for hundreds of millions of dollars. Lobov claimed that he gave McGregor the idea and sued him for a cut of the profits. However, the judge didn’t agree and in the end, they became bitter enemies for nothing.
