10. Colby Covington
UFC star Covington is no stranger to the scandalous. In 2021 he went too far by claiming that he slept with fellow fighter Polyana Viana, describing the encounter in an extremely nasty manner. She denied it and responded: “I have never given room for any kind of comment or judgment about my personal life, but it is not for me to judge the person’s attitude. I feel sorry for those who act in such a low way to try to promote themselves. It is revolting.”

Meanwhile, the fan reaction was surprisingly vocal. Many of them took aim at Covington. @FaGalen wrote: “This behavior requires intervention from the UFC. Colby’s ‘shtick’ crossed the line several times in the past IMO, but Dana can’t allow him to sexually harass a colleague in broad daylight, on Twitter, for everyone to see and on the record. If this isn’t the line nothing is.”
