ABC/Randy HolmesBillie Joe Armstrong can now play beer pong, thanks to Post Malone.

The Green Day frontman attended a show in Oakland, California Thursday by the “Circles” performer, and met up with him backstage. According to tour photographer Grady Brannan, who witnessed the meetup, Posty took the time to teach Armstrong the popular drinking game.

“We taught Billie Joe Armstrong how to play beer pong tonight,” Brannan wrote in an Instagram post accompanying a photo of himself alongside Armstrong and Malone.

“Green Day literally raised me and I’m still star struck,” the photographer added.

Armstrong also posted a photo of himself and Posty on his own Instagram.

“Great show!” he wrote in the caption.

Post Malone is currently on tour in support of his new album Hollywood’s Bleeding, featuring the Ozzy Osbourne collaboration “Take What You Want.”
