It's not long until Justin's new film is out in the UK but in New York they were treated earlier. Here's Bieber at his film premiere in New York with his mum.
Is this a new look for Justin? Maybe not, but he needs these 3D glasses to watch his new film.
Justin seems pretty excited about taking the movie world by storm - here he's talking to journalists in Toronto, Canada, a day before the New York premiere.
And here's Justin with his family in Toronto too - sister Jazmyn, dad Jeremy and mum Pattie.
His new film Justin Bieber: Never Say Never is on Friday 18 February in the UK. Newsround will be at the UK premiere, so watch this space...
