Disturbed frontman David Draiman has been living, shall we say, the high life on his current vacation in Amsterdam, and in recent days has been chronicling his pot-fueled escapades there on social media.
But it's not all fund and games: After learning that Justin Bieber was in the very same city, Draiman decided to throw down a weed gauntlet to the pop star.
"Hey @justinbieber, I hear you’re in #amsterdam! So am I!," Draiman wrote. "I challenge you to a smoke off!!!"
As for whether Bieber will accept the "Fire It Up" singer's challenge? Social media, and the world, awaits.
