26. Conor McGregor
Irish MMA fighter McGregor is ‘notorious’ for his anger problems. This affected him negatively in 2019 when he encountered an annoying fan outside of a Florida nightclub. The former double champion became frustrated because the so-called fan continued to follow him and his entourage around. Finally, it came to a head outside of the Miami event space when McGregor grabbed and smashed the man’s phone.

Needless to say, the ‘victim’ was delighted with this tantrum because he sued the Irishman. Police arrested the UFC fighter and he spent the night in a precinct. In the end, he settled out of court. But this was only after it became global news and McGregor endured more commentary on his unstable mind. In sum, McGregor can’t avoid trouble even when he isn’t looking for it.
