Rapper Blueface won his Bare Knuckle Fighting Championship exhibition match Friday night against TikToker Kane Trujillo, but it was anything but a total crowd-pleaser, because one disgruntled fan jumped in the ring swinging ... and all hell broke loose.
In what was billed as a battle of the influencers, Blueface crushed Trujillo ... winning a lopsided victory by decision. As he celebrated -- hand up in the air -- the fan jumped the ropes and, it looks like one swing made contact with the rapper.
