Paramount Pictures, MTV Films and Bieber's record label, Island Def Jam, say the 16-year-old pop star has signed on to appear in a feature film about his life and career.
The yet-to-be-titled movie is set for release on "Valentine's weekend" of 2011, the companies said Tuesday.
Bieber will also be producing the film, along with mentor Usher, manager Scooter Braun and Island Def Jam Music Group chairman LA Reid.
The movie will offer a "VIP backstage pass" into Bieber's life and will feature 3-D footage from his "My World 2.0" concert tour.
The ubiquitous teen sensation is also bringing his life to readers: HarperCollins announced Monday that it will publish his memoir in October.
