To be fair to Justin Bieber, he does have quite a mature head on his shoulders for someone who is only 18 years old. It’s only every now and again that he does something silly that reminds us that he is a teenager. He has been talking about how he finds it hard to be a role model – as he cannot live a perfect life. He said: "You know, there's a lot of people that look up to me and I'm not always gonna be perfect. At the end of the day I'm 18 - sometimes you've gotta make bad decisions to learn from them." And he did have some wise words about fame. He said: "I think it's all about who you surround yourself with and keeping all those good people close to you. And having those people telling you not to be full of yourself," Oh, we’d love to be the person to tell Bieber to not be full of himself. Like we say, and like he admits, he does do the occasional silly thing though. Just this week, he made a bit of a fopar at the Tribeca film festival. After all the talk of engagements and weddings and how he thinks he is too young, blah blah, he then goes and creates a lot of gossip by wearing a ring on his wedding finger. He was actually on stage wearing the ring, so everyone saw. His manager spotted the mistake straight away and was obviously very aware of the consequences. He said: “I just realised that he's wearing a ring on his ring finger. So after we leave here he's not engaged, he's not married, but I'm going to have to deal with that later." Bieber laughed afterwards and said: "Didn't even realise that, sorry guys. That's not what I was going for, a long time coming, guys. Why didn't anyone tell me?" He then moved it to his other hand!
