Greg Hardy is winning over some of the biggest female fighters in the UFC -- including Amanda Nunes and Rachael Ostovich -- and he tells TMZ Sports their support means the world to him.
Greg's past is no secret ... he was accused of domestic violence against a woman back in 2014 and initially convicted. The conviction was overturned in 2015.
There was a big controversy when Hardy fought on the same card earlier this year as Rachel Ostovich -- who was the victim of a brutal domestic violence attack .
