McGregor lashed out at Lobov, calling him a bastard.

Conor McGregor, the former UFC champion in two weight categories, "hit out" at his former friend Artem Lobov.

"Born in Russia, but you live in Ireland on welfare. You rat bastard! Your country is in a state of military conflict and you are hiding in Ireland on benefits. Your day will come, remember my words," - wrote McGregor on social networks.

Recall, earlier Lobov filed a lawsuit against McGregor in an attempt to sue him for money. After that, their friendship came to an end.
