Post Malone Teaches Green Day’s Billie Joe Armstrong How To Play Beer Pong

If you can believe it, Green Day’s Billie Joe Armstrong didn’t know how to play beer pong…that is until Post Malone taught him.  Armstrong recently attended a Post Malone show. Footage of a backstage meet-up was captured for Instagram.

Photographer Grady Brannan captioned the picture saying, “Two a**holes and a rock’n’roll legend… We taught Billie Joe Armstrong how to play beer pong tonight…Green Day literally raised me and I’m still star-struck.” The photo of Billie Joe playing beer pong allegedly for the first time is on Brannan’s page.
