Comedian Kathy Griffin is becoming the go-to gal for playing lesbian on TV these days. First Griffin played a strident lesbian activist in a fairly offensive to lesbians episode of Law & Order: SVU and now she's slated to guest star as a lesbian on the NBC comedy Whitney, starring Griffin’s pal Whitney Cummings.

In a video promo for the show Griffin chats about her Whitney appearance saying that Cummings was incredibly kind and welcoming, having sent Griffin a bouquet of flowers for her first day.

“I think Whitney Cummings and I are dating,” Griffin jokes. She adds that if she were a lesbian in real life that Whitney Cummings would be at the top of her list.

Here’s Griffin on playing a lesbian on Whitney and on her relationship with Cummings.
