Bare Knuckle Fighting Championship Knockouts Girl Amber Fields unzips her skimpy one piece while promoting Friday night's BKFC 19. That fight card features the rematch of former UFC fighters Paige VanZant and Rachael Ostovich. As Paige said, "come for the boobies, stay for the violence." You can add stay for the Knockouts Girls as well. Amber brings a ton of heat wherever she goes.
