Biebs looks kinda funny behind bars! Can you imagine if he actually went to jail? He probably wouldn't even last a day! Or would he? We could see that one going two dramatically different ways...

The teen pop phenom was spotted leaving a studio in Hollywood yesterday, and he's been holed up with producers Dark Child and Kirk Franklin. Justin has been preparing for his highly-anticipated Believe tour, which kicks off in Glendale, Arizona on September 29. Though he has a month off for most of December, the concert series runs through April and makes stops in 86 different cities.

Not only has the 18-year-old singer been working on his tracks, but it looks like he's trying to get in tip top physical shape as well. "workout...then rehearsal. #FOCUSED," he tweeted the other day. Wonder how much he's benching these days?
