Preview of Kathy Griffin and Mariska Hargita Locking Lips on SVU

Kathy Griffin will guest-star on next Wednesday's episode of Law & Order: SVU as a lesbian activist, and a sneak peek of her episode -- and her lip lock with Mariska Hargitay -- is already online.

In the clip, it appears Hargitay is checking in on Griffin, who is in protective custody. Griffin plants one on Hargitay, who quickly tells her that she's flattered but also not gay.

"Come on, I mean ... the job and the gun and the attitude," Griffin replies. "You're like Ellen, Joan Crawford, and Calamity Jane all rolled into one. If you can balance a checkbook, I'll throw in Suze Orman."
