Kathy Griffin and Mischa Barton to Guest Star on SVU

Law and Order: SVU has a couple of interesting guest stars lined-up. First, Kathy Griffin announced during her last NYE gig for CNN that she would be appearing on the series. And it looks like she is already taping her guest stint since she tweeted the following yesterday, “Today was my 1st day of filming SVU. Why does Chris Meloni keep offering me lube?” Typical Kathy.

Today, Kathy and the crew are filming at 3rd Ave and 24th St in Manhattan. But she won’t be the only special guest star joining the cast in the coming weeks. It was announced yesterday that after her hospitalization last summer and the downfall of her CW series The Beautiful Life in the fall, Mischa Barton is getting back in the saddle. The O.C. actress will guest star as a hooker on the March 3rd episode of SVU. Apparently, her character, Gladys, has a secret which will create some trouble for Benson (Mariska Hargitay).
