When and where: July 2013, Instagram

It's tough to find a picture of Justin Bieber post-2012 with a shirt on. Which is miiighty reminiscent of Marky Mark (aka Mark Wahlberg) circa 1991. Plus the backwards cap and the visible tighty-whiteys are a dead giveaway. Does this mean he'll go the way of Marky Mark and drop music to pursue a pretty good acting career? America can only hope.
