I definitely know Whoopi Goldberg is a Bisexual because she has said it on The View and she has kissed at least four females in her films. She just makes me happy all the time.

Is Oprah Winfrey a Bisexual too? I wanna know now>

Whoopi has been married several times too so she's even like many of us in here.

Wow I didn't know Whoopi is bisexual shows you how much I know, I 'think' Oprah's bisexual, she's never been married.

Angelina Jolie.

Billie Joe Armstrong (Green Day) has said that he is:

“I think I’ve always been bisexual,” Armstrong says simply. “I mean, it’s something that I’ve always been interested in. I think everybody kind of fantasizes about the same sex. I think people are born bisexual, and it’s just that our parents and society kind of veer us off into this feeling of Oh, I can’t. They say it’s taboo. It’s ingrained in our heads that it’s bad, when it’s not bad at all. It’s a very beautiful thing.”

I really like his viewpoint on it. There's a whole article in an issue of The Advocate (which I can't find at the moment), so if you run across it, it is good.
