Only 17 and a multi-million dollar superstar, Justin has said he would like to marry at age 25 or 26.
Quoting J.B: "Well, by 25 or 26, I want to see myself, like, married or start looking for a family," Bieber says. "I want to be a young dad. I want to be able to have done what I wanted to do - to be successful, to do a movie or whatever."
He's currently dating the "wizard of waverly places" teen star Selena Gomez and if all goes well, who knows what will happen in 5 years.
