Justin Bieber Birmingham uk singer hotel nia Mr. Paparazzi

There's no stopping teen sensation Justin Bieber ... even at the box office! The 16-year-old's docu-style 3-D film Never Say Never has grossed over $64 million, according to Box Office Mojo. No wonder he's in such a great mood while leaving his Birmingham hotel in the UK before his big show tonight.

This incredible box office total has earned Biebs' flick the #3 spot on the top-grossing documentaries list of all time. You go, boy!

March of the Penguins currently holds the #2 spot with $77 million, but analysts say Never Say Never will be taking that spot in no time. As for the #1 grossing docu of all time, Michael Moore's Fahrenheit 9/11 holds the spot with $119 million.

Just last week, Never Say Never's director's cut was released ... bringing in another $9 million.

Some Hollywood insiders are saying Bieber could be a possible Oscar contender next year. Whew! See which other documentaries Bieb's film has surpassed at the box office ... after the jump.
