NFL star Chad Johnson/Ochocinco was a likeable enough guy during his appearances on Basketball Wives while he was dating star Evelyn Lozada, but it’s what happened off camera shortly after their wedding that earned him a spot on this list.

About a month after their July 2012 wedding, Johnson was arrested for allegedly headbutting Lozada during an argument, one that was reportedly sparked by a receipt she found for a box of condoms. He was arrested, and she promptly filed for divorce a few days later, saying that their union had been “irretrievably broken.” For a good month, he pleaded for forgiveness, and even got Lozada’s face tattooed on him in an attempt to win her back, but the damage had been done, physically and emotionally. The divorce was officially finalized in September.

On a positive note, Johnson has apologized and expressed regret. But we're still talking about a professional athlete who knows exactly what his body can do.
