First a book, now a film!

16-year-old pop sensation Justin Bieber will star in a 3-D film about his life so far.

Slated for a Valentine's Day 2011 release, the as-yet-untitled film is a feature biopic with footage from his current tour, a Paramount rep explained to Us.  Davis Guggenheim -- the Oscar-winning documentarian behind An Inconvenient Truth -- will reportedly direct.

Bieber announced the "incredible news" on Monday via Twitter. "This is so sick!! Gonna come out in theatres Worldwide Valentine's 2011!!! I'm taking this thing worldwide thanks to u all!! Hyped!!"

The "Somebody to Love" singer added in a statement: "When the idea for a movie first came to us, we knew immediately this was our chance to give something very special back to the all fans who have been a huge source of inspiration and support throughout my entire career thus far. They simply make my dreams come true everyday. I cannot wait to share all the great experiences I've had over the last few years with them."

It's not Bieber's first foray into the dramatic arts: he plays a troubled teen on the upcoming season of CSI.
