The undoubtedly straight Joan Rivers claims she shared a kiss with another woman in a new episode of Joan and Melissa on WeTV. 

Rivers elaborates on the experience on Today, where she says she was out to dinner with Lily Tomlin and Jane Lynch when she found herself admiring a female dinner companion, and ended up locking lips.

"It's like the Katy Perry song," says Rivers on Joan and Melissa. "I kissed a girl, and I don't know if I liked it, [or] I didn't like it. I woke up this morning with an incredible urge to play golf."
