Justin, with director Jon Chu, talks about Never Say Never'
Justin Bieber's new movie Never Say Never is important to the star because he reckons it really shows the world what he's about.
The Canadian singer said the 3D film will uncover "how I got here and what struggles I've been going through."
Justin Bieber said: "There's so many people who have tried to tell the story about my life but haven't really summed it up correctly.
"I just wanted the world to see that I'm a regular 16-year-old," he added.
Justin's family also feature in the movie, which hits UK cinemas on 18 February.
He revealed that his grandmother's musical too: "She plays the piano, plays the guitar, she sings and she's really talented."
Never Say Never's director is Jon Chu, who also directed Step Up 3D and Step Up 2: The Streets.
