An ex-fiancee of Charlie Sheen has sued the actor claiming he didn't disclose he was HIV positive until after they had sex several times and was physically and emotionally abusive during their relationship. Scottine Ross, a porn star who performed under the name Brett Rossi, sued the actor on Thursday for assault, battery and intentional infliction of emotional distress claims. Her lawsuit states she and Sheen had sex five times before the actor told her he was HIV positive. The "Two and a Half Men" star publicly disclosed he was HIV positive last month but said he disclosed his status to all his sexual partners. He also vowed that he would not pay to settle any claims from sexual partners claiming he exposed them to the virus that causes AIDS.
