I've Been Told That Billie Joe From Green Day Is Bi Sexual Is That True?

I've never heard that.

After the release of American Idiot, Billie Joe, as a stunt more or less, said that he was bi-sexual. He did this just to mix things up with the fans and to make him seem more interesting. It's not true.

In an interview with The Advocate magazine (1999) Billie Joe stated:
"I think I've always been bisexual. I mean, it's something that I've always been interested in. 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."
He has also stated that the song, "Coming Clean" is about coming out and did an interview with Instinct magazine (2004) speaking about homosexuality. He is married,has kids and is bisexual.

I'm pretty sure he's married, although i suppose that doesn't mean he isn't. But i've never heard he is
