In the story, Bieber also offers his views on sex.
"I don't think you should have sex with anyone unless you love them," he told the magazine.
Asked if he believed in abstinence before marriage, Bieber said: "I think you should just wait for the person you're ... in love with."
The "Baby" singer is reportedly dating teen star Selena Gomez.
Rolling Stone reporter Vanessa Grigoriadis also asked Bieber about his stance on abortion.
"I really don't believe in abortion," he told the magazine. "It's like killing a baby?"
When asked if it was acceptable in cases of rape, he told Rolling Stone: "Um. Well, I think that's really sad, but everything happens for a reason. I guess I haven't been in that position, so I wouldn't be able to judge that."
