Justin Bieber Talks Abortion, Spikes His Hair for Rolling Stone Cover

Justin Bieber may only be 16, but he speaks out about some surprisingly adult issues -- sex, abortion and health care -- in his upcoming Rolling Stone cover story, in which the pop star appears with his famous haircut spiked and styled into a more rock-star (or "Twilight") inspired look.

"I really don't believe in abortion... It's like killing a baby?" the pop star, who is a self-proclaimed Christian, tells writer Vanessa Grigoriadis. When asked about abortion in cases of rape, the singer offered a more nuanced opinion: "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."

Bieber also laments the lack of universal health care in the U.S. and says he doesn't expect to ever become an American citizen. "Canada's the best country in the world," he says. "We go to the doctor and we don't need to worry about paying him, but here [in the U.S.], your whole life, you're broke because of medical bills."

On sex, Bieber says couples should hold off on having it until they find someone special. "I really don't think you should have sex with anyone unless you love them," Bieber says. "I think you should just wait for the person you're... in love with." As for Bieber's rumored romance with fellow pop star Selena Gomez? At one point during the interview, the singer opened his laptop, the background of which featured the two stars against the backdrop of an orange sunset.

Elsewhere in the story, Bieber's vocal coach Jan Smith addressed the changes in the singer's voice that are the result of puberty. "He's got a nice tone to his voice now," Smith says. "It's a good texture, but it doesn't sound like what his fans think he sounds like. He'll get four octaves eventually. He's still young."
