Justin Bieber

When he's not signing Anne Frank's guestbook or breaking up and getting back together with fellow teen pop idol Selena Gomez, Justin Bieber also performs arena tours around the globe. This time around, the Biebs hits Saitama Super Arena (just days ahead of the Backstreet Boys, weirdly enough) for a gig in support of last year's Believe. Tickets go on general sale on July 27.
