As most of you have heard, "The Real Housewives of Beverly Hills" star Taylor Armstrong's estranged husband Russell Armstrong was found dead of an apparent suicide. According to reports, Russell hung himself in the home he shared with his roommate. Police say they have not yet found a suicide note. Taylor recently filed for divorce last month from her husband, citing Russell physically abused her. Sources are coming out and claiming Russell may have committed suicide to avoid a long divorce process and to keep the graphic details of his marriage to Taylor from ruining his professional image. For now, Taylor is said to be distraught over her estranged husband's death and wishes for privacy in order to break the news to the couple's 5-year-old daugther Kennedy. Russell was 47 years old.
