The "My Life on the D-List" star, usually known for her comedy, visits the gritty crime drama on Wednesday, March 3rd episode at 9 p.m. Et/Pt on NBC.
The episode titled "P.C." revolves around a woman from a growing lesbian community who's been found bleeding from the neck. When she dies at the hospital, Det. Benson (Hargitay) and Stabler (Chris Meloni) investigate and come across the death metal band Vampyre Sacrifyce, whose lead singer bites girls and sings about violence to women.
Kathy Griffin plays Babs Duffy, a member of a lesbian rights group that believes the victim's death was a result of police neglect.
Here she is with Benson.
"The heart wants what the heart wants." We knew Griffin wasn't going to play this straight -- in more ways than one!
