How do you talk to Billie Joe Armstrong?

Umm.

Talk to him like you would talk to any other person? If you mean to meet him, i think there isn't much of a chance that's going to happen, unless you live in Oakland Ca. And happen to see him somewhere around there. Or you befriend his son, and you'd have to be one of there ages.

Sorry, but i doubt it will happen. But kudos to you for trying and if you ever do, it's okay to cry. (:
