Post Malone headlined the Oakland Arena on Thursday November 14th, and was met by Green Day's Billie Joe Armstrong backstage. Armstrong shared a shot of the two together, captioned "Curly hair. Great show!"
Billie Joe's photo only tells half of the story though, as photographer, Grady Brannan, noted that the Green Day singer was taught how to play beer pong backstage. "We taught Billie Joe Armstrong how to play beer pong tonight," he wrote. "Green Day literally raised me and I’m still star struck."
Billie Joe has made it a habit to make it out to big shows in the Bay Area with today's biggest artists. Back in May he met Billie Eilish for the first time at her show in San Francisco. The two have since interviewed each other for Rolling Stone.
Post Malone wraps up his tour with two shows at The Forum in Inglewood, California next week. Green Day are set to start their HELLA MEGA Tour in July.
