Never Say Never is the film loads of you have been waiting for, and as fans waited for Justin to turn up on the red carpet there were some pretty excited faces.
Some fans had waited all day for a glimpse of the Biebster - Brit winner and Bieber fan Jessie J hit the red (well, purple) carpet before the man himself.
And then the fans got what they were waiting for - Justin posed for photos before heading into the cinema.
He even had time to sign a few autographs before the showing of the 3D film about his rise from normal kid to superstar.
But when Justin arrives - so does the noise! Ricky was on the purple carpet for Newsround - and it looks like the screaming was all too much for him!
Ricky met some of the guys waiting for a glimpse of the superstar, including this guy - who we think looks like a bit like a mini-Bieber!
And look how close Ricky got to the man of the moment! He took this snap - the lucky thing!
Justin says he hopes people will find the film inspiring, as it shows that with enough talent and hard work anyone can make it.
And it wouldn't be Justin Bieber without some messing around! In the cinema he headed straight for the food and served himself! Cheeky!
