Taylor Armstrong

In her first interview since her husband's suicide, Taylor Armstrong will appear on Entertainment Tonight and discuss bruises that she says were caused by her husband, Russell Armstrong.

Armstrong's sit-down with Nancy O'Dell will air Tuesday, Sept. 20, a week after the entertainment newsmagazine posted pictures showing The Real Housewives of Beverly Hills star with a black eye. The show is doing an investigation this week into said black eye, as well as other alleged bruises.

Remember other celebrities we lost in 2011

A source tells ET that Taylor underwent Lasik eye surgery on July 5, but that her corneal flap was dislocated several days later when Russell hit her. Taylor did not make any public appearances until Aug. 1.

Taylor filed for divorce from Russell in July and told People their marriage was "abusive" in an interview shortly after she filed.  "Did I push her? Yes, maybe things happened in the heat of the moment, but it was during a time in our lives that was not characteristic of who we were," Russell told People at the time. "This show has literally pushed us to the limit."

Russell committed suicide on Aug. 15.
