Justin Bieber’s latest Rolling Stone cover leaked on Twitter! The August issue of the mag was supposed to hit shelves on July 20th, but the cover leaked via a Bieber fan who tweeted a photo of her subscription. This is Justin’s second Rolling Stone cover, the first was February 2011, and both covers feature Justin wearing a white tank top. The photo shoot is said to include lots of Justin’s signature fabric, denim, and the pop superstar playing the guitar. Fans will see Justin’s mature side in the mag; he’s got a new look and attitude to match his latest singles. Bieber is even starting to draw comparisons to another Justin, Justin Timberlake! A pretty flattering comparison considering Timberlake’s rise from boy-bander to successful solo artist and movie star. Congratulations to Justin on another amazing cover, we can’t wait to see what he does next!
