The Canadian pop superstar, 18, has been dating actress Selena Gomez for several months.
When asked by French newspaper Le Parisien whether he has plans to propose to Gomez, Bieber responded: "No, I am too young."
Confessing that he is unsure whether his current relationship will last, Bieber added: "One day, I will get engaged, when I will have found the right person in five or ten years."
However, he insisted: "It doesn't mean that Selena is not the right person though, she is going to kill me if I say that!"
Of the public nature of their romance, Bieber added: "It is not easy to be so young and to have a relationship with someone that doesn't stay private.
"But well, I am a public personality, it is what I wanted, so I have to deal with it."
