Garbrandt stormed off from a television interview with him and Cruz on Wednesday, threatening to come to the room where Cruz was sitting. The exchange aired on The Fight Network in Canada.
When talk between the two turned to Garbrandt's girlfriend and Cruz commenting on her Instagram, it got heated.
"She shouldn't be hollering at me on social media," Cruz said. "Keep her to yourself. As far as I'm concerned, I did you and her a favor. She obviously wears the pants in the relationship or else she wouldn't be having to defend you."
Garbrandt then said he'd go to Cruz at that very moment.
