It’s not enough for Justin Bieber to dominate the pop music industry and write a book — the teen sensation has a larger-than-life 3-D movie in the works, too. To announce his director, Bieber combined the two forces that catapulted his career into the stratosphere: YouTube and Twitter.

“I’ve been wondering, why’s this guy following me around?” Bieber jokes in the video (which helpfully has his twitter handle in the corner, as if any of us could forget) before introducing director John Chu to his legions of loyal Biebettes.

]]>So if you guys wanna be IN the movie don’t worry you don’t have to have tickets to the concert. Just keep checking up with me for updates…” Chu tweets. Follow Zap2it and @cadlymack on Twitter and Zap2it on Facebook for the latest TV, movie and celebrity news.
