"I'm not trying to kill nobody. My whole thing is that I'm tryna break some faces, so come October 4, I'm going straight to this dude and I'm breaking his f***ing face."

"From what I heard, because I wasn't in Miami, he was acting all big and bad and tough, I was over here having COVID and I was dying here in Vegas," Lopez says.
