PHOTO: Mike Posner in London, Backstage at Justin Bieber’s ‘Believe Tour’ Concert

Here’s a photo of Dan Kanter, Musical Director and Guitarist for Justin Bieber, and Mike Posner backstage at JB’s ‘Believe Tour‘ stop in London, UK on March 4. I don’t know why Mike snuck out of the US and went to London, UK without telling anyone, LOL. Not sure if he’s just there for JB or there working on his own music or for someone else.
