Justin Bieber at the 2011 Grammy Awards (PHOTOS)
Justin Bieber is all grown up!
The 16-year-old singer hit the Grammys' red carpet on Sunday and reminded us that he's not a little kid any more, as the Biebs looked smooth in a white tux.
It was a big weekend for Justin -- not only is he nominated for Best New Artist at Sunday's ceremony, but Never Say Never, his 3-D concert spectacular finished with $30.3 million at the box office.
