Kathy Griffin will guest star on an upcoming episode of Law & Order: Special Victims Unit, TV Guide has confirmed.

The 49-year-old funnywoman, who campaigned for same-sex marriage on her Bravo series My Life On The D-List last season, has been tapped to portray a lesbian activist on the Feb. 6 episode of NBC’s long-running crime drama.

SVU executive producer Neal Baer revealed the Emmy winner as the series’ next big guest star on Twitter Tuesday, after asking fans to take part in a Hangman-type game to guess who would guest star.

Griffin was recently announced as the host of the dance competition Let’s Dance, which was shelved by ABC earlier this week.
