When asked if he would agree to judge a TV talent show if asked, he said that he may do so in a number of years' time.
"Maybe in a couple of years," he told ITV1's Daybreak. "Five years or something like that could be cool."
The 'Baby' singer also admitted that he may "make mistakes" as an 18-year-old star, but hopes to remain a "role model" to young fans.
"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 like to have gone into space for NASA.
"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 Bieber revealed yesterday that he would like to collaborate with British boyband One Direction in the near future.
His new single 'Boyfriend' has been released in the UK ahead of its original scheduled date of May 20.
