Justin Bieber has revealed that in the future he would be interested in judging the US X Factor.

The American popstar has said he would consider the role in a number of years' time.

He told Daybreak: "Maybe in a couple of years, five years or something like that could be cool."

The singer also admitted that as he is only 18 years old he may make mistakes, but hopes he will be a "role model to his young fans.

He said: "I see myself as a role model, which can sometimes can be stressful. I'm 18 now, so I'm gonna make mistakes.

"I'm not perfect, sometimes things happen. I'm human, people have got to know that I'm gonna make mistakes."

Bieber added that if he had not become a singer he would have liked to have joined NASA and gone into space.

He said: "I'd probably be an astronaut, because I want to go to space. Ashton Kutcher's doing that. I don't know if I want to spend that kind of money."

Justin has also admitted that he would like to collaborate with UK boyband One Direction in the future.

真人选秀节目《X达人秀》（The X Factor）美国版正在四处寻找新评委人选，欧美流行小天王贾斯汀·比伯（Justin Bieber）也有意加入评委的行列，不过不是现在，而是在5年之内，因为他担心自己现在的人生阅历不够丰富，有可能因此犯错而导致评判不公。

近日在参加ITV电视台的访谈节目《拂晓》（Daybreak）时，主持人询问贾斯汀·比伯是否有可能出任真人选秀节目《X达人秀》的评委，对此他的态度是：“可能在几年之内我会接受邀请吧，我觉得5年左右将会是个合适的时机。”尽管已经是亿万青少年的偶像，但贾斯汀·比伯毕竟只有18岁，他承认自己有时候还是会因为年轻而犯错，所以在短时间内不会出任选秀节目的评委，他担心会因为自己阅历不足而导致在评判时出现偏颇。

对于自己在阅历上的问题，贾斯汀·比伯非常大方的承认：“我将自己看做青少年的偶像，有时候这会给我带来额外的压力，但我只有18岁，我要允许自己犯错误。我并不是完人，有时候也会有考虑不周的地方，我也是一个平常人，人们知道我在某个时候也会犯错。”

如果没有进入演艺圈，贾斯汀·比伯最期待的工作就是成为太空宇航员：“我有可能成为一名宇航员，因为我对太空非常向往。艾什顿·库彻（ Ashton Kutcher）已经体验过外太空了，但我不知道自己是否会掏钱做这种旅行。”
