Oscar de la Hoya may be in rehab for substance abuse, but now someone is threatening to release just how bad the former boxing champ's addiction was. Pictures of the Golden Boy on a cocaine binge are reportedly being shopped around. Photos of de la Hoya at a Vegas party allegedly show just how scary his addiction had become. Oscar is seen using a rolled up bill to inhale lines of a white substance off a plate on a table, and were shot a few weeks shy of the announcement that he would go into rehab. TMZ reports that the former boxer is aware of the pictures, but there has been no word from his rep.
